portable rock crusher & rock crusher manufacturer
Technically, portable rock crusher is a set of flexible, easily-transferred and self-contained equipment. It is a combination of devices installed in stone crushing plants and sand making plants for material feeding, crushing and screening. Besides, this kind of mobile rock crushers is widely used in gold mining and construction waste processing. It could be classified into two variations: semi-portable stone crusher and tracked crusher, according to the way it moves down roads.
Portable rock crusher is a kind of crushing equipment which could move down roads over wheels or crawler to operation site for processing materials without a pile driven and prepared (Piledriving is to sink piles into deep ground to offer an extremely stable foundation for the building above). A complete mobile crusher plant commonly consists of wheels/crawler, a fixed crusher, sometimes grinder or pulverizer, vibrating screen, movable crusher frame, which not only perfectly demonstrates a self-contained and agile structure, but also unveils the versatility of crushing and screening. So, the portable concrete crusher is the most advanced crushers among all crushing equipment.
Flexibility highlights and separates portable rock crushers from the stationary machine. A portable rock crusher is available for various terrains and could be driven by both diesel fuel and electric generator, which implies that power supply wont be such a challenge for the places where a mobile stone crusher machine is launched. (Analysis of investment on power supply will be elaborated on later) Besides, according to the real project demands, the portable concrete crusher can also be customized to a small scale rock crusheror big ones, which totally depends on how many materials you have and productions you want.
How much it will take to invest in a mobile rock crusher? Hongxing Machinery portable rock crushers provide different models of rock crushing machine to meet customers' needs whether hatever you use it to process gold or process construction waste. And there are also very cute mini rock crusher machines for your small-scale crushing project.
The workers and facilities assigned on pile driving could be cut down because there is no need to prepare one for a portable rock crusher. In addition, a portable rock crusher usually comes with a PLC controlling system to offer a simple operation, and three men could get it under control at siteone takes charge of maintaining, one is the loader driver, and the last is in charge of real-time supervision, which explains why its said that a mobile rock crusher is a money saver. A mobile rock crusher could be driven to operation site and gotten in production immediately, not to mention that it could deliver end products to where they are wanted to be.
According to research, it needs 70 RMB (11 dollar) to truck a ton of granite in China. Thats to say, approximately 11000 dollar needs to be spent only in delivering 1000 tons of materials, let it alone adding the end products freight cost. While a portable rock crusher will spare users from such kind of worry, compared with a fixed crusher, as in whats shown in the chart below.
Product Quality: Its often said that how much you'll spend depends on quality, so is in the case of a portable rock crusher. More importantly, only a manufacturer pulls more advanced technology and high-quality materials as well as more senior engineers on researching and designing such high-end product can an unrivalled mobile stone crusher come into being. So, to ensure a long term stable working, people have to purchase the high-quality cruhshers installed on the portable rock framworkno matter it is jaw crusher or impact crusher, which can bring you the largest working capacity and profits.
Supplier: there are agents and mobile stone crusher manufacturers who both supply portable rock crusher in the domestic and foreign market. The agents usually refer to those people who buy products from manufacturers and sell them to end buyers to withdraw a sum of commission during the whole transaction, while the portable crusher manufacturers are those people who make products and directly sell them to end buyers. Nowadays, many people choose buy rock crushers whatever it is portable rock crusher or fixed rock crusher from manufactures not agents because the former can offer best service, product quality gurantee, and free operation trainning while the other just sale it out and then responsible for nothing.
Market: With the booming development of construction, cement and chemistry industry, this kind of more flexible and mobile rock crusher is in greater and greater demand in the market, which has created a stage where some of manufacturers play a villain role in lifting the price of portable rock crusher to a new bar to squeeze as many profits as possible.
Diesel engine: the engine which is usually affiliated with the equipment is started with diesel fuel consumption to generate power used for a portable rock crusher to move and crush. From Google, a database penetrating every walk of life, it is easy to learn that about 210 grams of diesel fuels has to be consumed for per kilowatt of electricity and 800 grams of them make a liter even. Then in China, each liter of diesel fuel is sold for 6RMB (1 dollar), a number almost coinciding with that in the international market.
Generator-driven pattern: in China, a 100kw generator could produce 1 kilowatt of electricity per hour, and 1 KWh industrial electricity needs to be paid approximately 1 RMB(0.6 Dollar) for, as well as a 100kw generator sold for 40,000-50,000RMB (5,953-7,400 Dollar). It should be noticed that if the generator-driven pattern is more suitable for an operation site, getting generator backups prepared ahead is definitely an awesome action.
From the diagram, it could be seen that the former pattern is more fitting for short-term projects, and the latter one is better used in long-term projects. Actually, each of power supply patterns has its own two sides. Generator-driven pattern proves to be friendly to environment where human reply on and could help users skip some trivial procedures, but raises a higher standard on operating cost; while diesel engine turns out to be more economical, but inevitably causes air pollution to environment. So which kind of method to take is determined by the final requirements.
As one of key parts of investing, the portable rock crusher machinemaintenance costmainly lies in turning the old and worn-off wearing parts into new ones. As a matter of fact, when it comes to maintaining some kind of crushing equipment, its all about changing the worn-off spare parts. The only difference is that each kind of machine gets its own wearing parts with different qualities. For example, it does take more investment to maintain a portable cone crusher than a portable jaw crusher, because the cone crusherwearing partscomes with higher quality and longer service life than those of a jaw crusher.
All in all, purchasinga portable rock crusher is just as important aschoosing the right crusher manufacturer. So, you have to take all things into consideration like the respons of its customers, the price of the rock crushing equipment, the shipping money, the service.
How does a portable rock crusher work? In general, it can work alone and also can team up with another crushing equipment. A portable rock crusher is a combination of crushing machines like feeder, crushers, transportation and screening equipment, just like a complete production linewith large capacity stone feeding bin and stone screening equipment.
Compared with the other ordinary crushing machines, a mobile impact crusher plant could not only show a good performance under the environment better for a stationary crusher, but also play an irreplaceable role in the short-term project that is operated in a complicated and terrible environment, or needs to be occasionally transferred from one location into another one for processing purpose. A portable rock crushing machine is a better choice for the people who are planning to make a higher bid, as currently advanced technology and premium materials have to be adopted to make it such a flexible rock crusher. What's more, there are many mobile crusher manufacturers who can draft the plans for you.
Portable rock crusherhas excellent mobility and adaptability of the working site, anditdoes not need much pre-preparation before the installation of the portable rock crushing station. Except that, the mobile rock crusher also has many remarkable advantages, such as high crushing efficiency, strong bearing capacity, stable operation, convenient maintenance and so on.
China Hongxing is a professional mobile crushing station manufacturer. The crusher equipment includes cone crusher, jaw crusher, impact crusher equipment, etc. There are many cheap and affordable rock crushing machines for sale. You can have a look at the product center where manufactures all kinds of rock crushing machines, such as crushing equipment, mobile crushing plants; construction waste disposal equipment; sand washing equipment; conveying screening equipment.
A portable rock crusher machine is more of a qualified helper for recycling construction waste and concrete in cities, especially for some small operation sites where construction waste piles up dispersedly, which could be explained through three easy-understanding reasons.
Moreover, a portable rock crushing machine is able to effectively ease industrial sand shortage through offering abundant premium manufactured sand and has been playing a chief role in current infrastructure construction industry.
Today, environmental issues are deeply rooted in the hearts of the people. The stacking and burying of construction waste will cause serious pollution to the surface and underground. In this way, it is very convenient for a portable rock crusher machine to handle construction waste. Due to the complex terrain of some construction waste dumping sites, the mobility of the portable rock crusher tends to be an excellent stone crusher machine to solve this problem. The construction waste processed by portable rock crusher can be recycled, and some recycled materials can replace the aggregate of sand and gravel, which reduces the exploitation of river sand and plays a major role in protecting the environment. Nowadays, the portable concrete crusher has effectively solved the problems on of management and protection of rivers and lakes. For example, in the past, we always saw construction waste occupied the road disorderly but now the portable construction waste can crush them efficiently in short time.
Environmental protection is the practice of protecting the natural environment by individuals, organizations and governments. Its objectives are to conserve natural resources and the existing natural environment and, where possible, to repair damage and reverse trends. --Wikipedia
With the increasing attention paid to environment protection, stricter and stricter requirements have been put on a variety of enterprises supplying mining machines. In order to keep down dust and noise level of a portable rock crusher in the middle of running, some methods could be implemented as below:
Dust-proof measures: An amount of dust mainly appears and flies around a portable rock crusher doing crushing. In order to avert such phenomenon causing severe air pollution to environment, a new cavity design offering great sealing performance, with addition of sprayer, has been adopted in making the advanced movable crusher to effectively prevent dust from snapping out and put restraints on dust rising separately during the whole processing, which successfully illustrates how eco-friendly a portable rock crusher could be.
Noise-proof methods: noise proofing for a portable rock crusher equipment is mainly reflected on turning down the noise source and adding noise-isolation cover. Take a portable impact crusher for example, its feasible for engineers to optimize manufacturing technique and adopt materials making lower noise when researching and developing the portable impact crusher to keep down the noise source through relieving machines vibration and friction. Besides, with the help of noise-isolation cover assembled on the impact rock crusher, noise could be significantly turned down when the machine is crushing and processing materials.
Apart from all of these ways to control dust and noise, a mobile rock crusher equipment also unveils good eco-friendly feature, which could be illustrated from two aspects: natural resources conservation and high efficiency. The former is attributed to its self-contained structure that takes less space to conserve land resource, and the latter is thanks to that it could move along routines to make it to the operation site where raw materials could gets crushed then. This could save adequate investment on transporting materials to the site for users and do little harm to environment, not to mention its convenient maintenance, powering saving and great return on investment.
A portable rock crusher could be at its most effective condition when the capacity is arranged at 80-400t/h, for its space-limited frame for containing and supporting other equipment pulls certain standard on the fixed crusher used with it, which indicates that a fixed crusher is not fitting for the carrying frame if its biggest capacity is under 80t/h or above 400t/h. A small or mini fixed crusher cannot take too much more of vibration and friction, while a big one fails to fit in the frame of a portable rock crusher. Therefore, if some projects such as coal mining, gold mining are located in the terrible environment, a 80-400t/h portable rock crusher equipment will be the best choice because of its flexibility and great efficiency.
As opposed to a fixed crusher, a portable rock crusher is not perfect for processing a large number of materials in large size. Because it happens to team up with a stationary crushing equipment to work together, like portable jaw crusher and portable impact crusher, portable cone crusher(used in secondary crushing) and the feeding opening designed for material entry is supposed to coincide with the feeding size of the stationary crusher whose total weight and dimension need staying in accordance with the frame, otherwise, numerously oversize materials fed into the machine will result in severe clogging condition even unexpected downtime.
Take the portable jaw crusher as an example, this kind of stone crushing plant can be applied to some materials with hardness less than 9 and humidity below 6%. In addition, the non-flammable and explosive materials are also suitable for processing with portable jaw crushers. And different models of the crushers suit for differet project scales. Apart from the generla big ones, there is also mini rock crushers which is mostly used to reduce very small materials at a limited space.
Actually, the installation of a portable rock crusher primarily follows several simple steps: delivering the machine to siteinstallationsoft operating (without materials)soft operating(with materials), and it could be literally put into operation if each of steps proves nothing abnormal. Sometimes, with the help of some manufacturers who is known for free one-stop service including product delivery, installation and personnel training and etc, it wont take more than a week before getting a portable rock crusher mining machine into mass production. Just like a fixed crusher, a mobile rock crusher equipment should be maintained every 20 hours in order to guarantee its uptime.
Semi-portable crusher (also for semi-mobile crusher) consists of two main parts: moving parts and working parts. The moving part includes chassis, legs and oil tank, and the working part is fixed on the former part and contains a fixed crusher and power units such as electronic control system. Only with the help of a tractor can a semi-portable crusher move flexibly.
Unique Features of Semi-portable Crusher
Only with the help of a tractor could a semi-portable crusher move
Fixed legs under the frame guarantee its reliable working condition and enable it to team up with large fixed crushing equipment to improve efficiency as a whole
With short wheelbase (wheelbase is the distance between the centers of the front and rear wheels), and small turning radius (the turning radius of semi-portable stone crusher is the radius of the circular turn that it is capable of making), it doesnt do harm to roads
With fine size and premium quality, its end products are easier to get recycled
Tracked Crusher is literally a kind of portable rock crusher or mobile stone crusher. With a tracked chassis, tacked crusher could move even make a turn flexibly under the remote control of PLC system touchpad. Like a semi-portable crusher, a tracked crusher could process 50-400tons of materials per hour as well.
Even though tracked crusher is not as good as a semi-portable crusher in terms of stability and efficiency, it could move freely without traction force and demonstrates greater mobility and agility than semi-portable stone crusher.
Secondly, tracked/portable stone crusher is more easily-transferred because it takes advantage of crawler to move flexibly and only needs the least time and manpower to get delivered to operation site with the remote control of intelligent PLC system touchpad.
Lastly, the chassis of tracked crusher is designed in a fully rigid tracked structure looking like a ship and reveals the following characteristics: good rigidness, unrivaled flexibility and great acclimation for mountains and wetlands. All of these features enable a tracked crusher to climb mountain to reach operation site, which makes it more perfect for mountain stone mining and open coal processing.
With the development of technology and society, portable rock crusher has being more and more popular and playing a crucial part in society.An oil-electric dual-purpose crusher is equipped with a dual-purpose sifter the portable rock crusher uses the best innovative design to set a new benchmark for communication and collaboration between crushing equipment and other ore dressing equipment.
More importantly, people and government attach much importance to the environmental protection, especially the heavy mining machine industry. The portable rock crusher machine manufactured adopts environmental protection design, reducing dust pollution and noise, which is a stone crusher with economic and environmental protection properties. Lead a new lifestyle starts with a flexible, agile and eco-friendly portable rock crusher equipment.
advantages of small portable rock crushers - hongxing machinery
With the continuous development of the construction industry and the changing needs of people, a variety of crushers come one after another. Recently, there is a new type of mobile crusher called a small portable crusher in the market. Compared with the large- scale mobile crusher, its physique is particularly small and looks like childrens toys. So why is it so popular in the mining industry?
Because of the general movement, its feed port, and discharge size have a certain range. Although most of them can be adjusted and to the minimum size in time, some small stones are still not able to be broken.
For example, a mobile CJ jaw crusher, its feed size range is 1500*1300-930*580, and the size of the material in your hand is less than the minimum size of 930*580, which means if you still insist on using general mobile crusher machine, the material will slide directly from the discharge port. Or the material can not be ideally broken to the perfect shape. Therefore, when it comes to this situation, a small portable crusher has to be used to meet the crushing requirements.
In summary, when you choose the machine, you must compare your material size with the size of the crushers import and export. The model is different, the body shape, the import and export size is different, and the homework is very good in advance. important.
The second important factor is the complexity of the crushing site. If the construction site or a quarry is small and complex, youll get some troubles when crushing stones. To install a fixed crusher, it is necessary to survey the environment first, then piling, installing the machine, testing the machine, which is very cumbersome. The small crushing operation itself does not take a long time, but the installation process has consumed most of the time, which is not the good result that the customers want, so they require a small mobile crusher.
The crawler- type or tracked small portable crusher is the most convenient, and can clime any difficult crushing site and be operated remotely. The output range is around 1-50t/h, which is also suitable for crushing a variety of materials, rotors, tiles, gold ore, and limestone. In short, in the face of complex sites, small mobile crushers not only meet the basic needs of customers but also improve efficiency and save costs and budget, which is one of the reasons that most people prefer.
In general, a small portable rock crusher is mainly used to process aggregates with very small production or gold ore crushing. There is a specification of the small portable jaw rock crusher in the following:
In general, the cost of the small portable rock crusher is much cheaper than the large-scale portable rock crusher. At the market, you may spend $66,666.00-$188,888.00 (according to Alibaba) to buy a normal portable stone crusher, but a small one would only account for about a quarter or one-fifth of that price. Therefore, you can get a reasonable-price small portable rock crusher, and would also be shocked at the best performance and efficiency that the small crushing machine brings.
the differences between fixed crushers and portable rock crushers - hongxing machinery
Various types of rock crushers for sale have been applied for a long time in the field of the mining machinery industry, which has played a very important role in the construction of large-scale infrastructure and mine development and utilization in various countries (especially in Africa).
The stone crushingmachine is mainly used for crushing large materials into small particles and small-sized materials to meet the requirements for the use of graded gravel in engineering.For example, in the process of making asphalt concrete, it is necessary to add stones of different particle sizes as a skeleton structure, which plays a role in supporting the road surface.
Most of the asphalt concrete aggregates are made by crushing a rolling natural stone through a crusher machine. After screening and pulverizing processes at all levels, the natural stone can meet the engineering requirements.
According to the production needs of different users and the site conditions, HXJQ has developed fixed crushers for sale and portable rock crushers for sale. The two types of stone crushing machines have their own advantages and characteristics. So what are the differences between the two crushing machines? Lets first look at a customer case:
Mark is a customer from India who wants a portable rock crusher for gold mining, but the gold mines mined by Mularck were not enough for the stone crusher site. After knowing about his production spot, the Hongxing Machinery sales manager suggested establishing a portable rock crusher production line. This production plan made the customer from India very satisfied, not only saved him a lot of budgets but also solved the problem of his small production site.
The body structure of the portable hammer rock crusher is compact, whose floor space can be reduced by 1/5. In addition, the finished product can be formed once, so the subsequent secondary crushing is eliminated, and the process tends to be simpler.
The noise of this crushing equipment is only 80-85DB, and the closed crushing method is adopted. In this way, the pulverized coal pollution and resource will be reduced, and the green emission standard can be achieved.
The portable crushingplant can be installed in the open air, which can be reached 300TPH. At the same time, the coal particles crushed and formed in one molding are uniform, and the climbing operation can be realized.
Fully automatic crushing operation mode, equipped with thin oil lubrication station, using oil-electric hybrid operation mode, freely selecting energy supply form, ensuring long-term stable operation; setting operation room, remotely controlling the portable rock crusher operation.
This customer case shows that portable rock crusher for gold mining is suitable for some uneven grounds, and it is more convenient and quick to walk freely, saving manpower and material resources. In addition, there are two types of portable crushing plants, namely, semi-portable crusher, and tracked crusher, which gives users a variety of options.
Mohammed is a customer from Zimbabwe who wants to process iron ore and his yield requirement tends to be 500 tons per hour. In addition, the iron ore that the customer wants to crush is lean iron ore with a hardness of 5.5-6.5, which is not easy to crush. While the fixed jaw crusher can process this kind of material with excellent performance.
From the above two customer cases, it can be seen that different types of crushers are suitable for different sites and materials. In order to maximize the crushing efficiency, the most suitable crusher must be selected. So what is the fundamental difference between a portable rock crusher for sale and a fixed crusher for sale?
The portable crushing plant is mainly used for metallurgical, chemical, building materials, hydropower and other materials that need to be relocated, especially for the operation of mobile materials such as highways, railways, hydropower projects, etc. Different configurations are required for the finished material. Hongxing Machinery portable rock crusher machine for sale has two types of crawler breaks and tire breaks. There are also some differences between the two mobile crushing stations.
The tracked portable crusher integrates feeding, crushing and conveying with one part, which has an advanced design, excellent performance, high production efficiency, convenient maintenance, stable and reliable work, etc. Tracked mobile crushing stations are widely used in many fields such as construction waste, rock, ore, and block road old asphalt concrete.
In conclusion, the portable rock crusher machine is like a small and medium-sized crushing processing plant, and its working efficiency and operating cost are better than the fixed crusher machines. The main crushers used in tracked portable rock crushers are mainly portable jaw crushers and portable impact crushers. The semi-portable crusher uses on-board traction, which enables the portable crushing plant to meet the mobility requirements both at the job site and on the road.
The fixed jaw crusher is commonly known as the tigers mouth, which indicates that this kind of stone crushing machine has a large production capacity. The crushing chamber of the fixed jaw crusher is composed of two jaws, which simulate the two movements of the animals to complete the crushing operation. The fixed jaw crusher machine for sale is widely used in the crushing of various ores and bulk materials in the industries of mining, building materials, roads, railways, chemical industry, etc. The highest compressive strength of the raw materials tends to be 320Mpa
Fixed impact rock crusher is mainly used for metallurgical, chemical, building materials, hydropower and other materials that need to be relocated, especially for the operation of mobile materials such as highways, railways, hydropower projects, etc. The fixed impact rock crusher can process materials with a side length of 100-500 mm and a compressive strength of up to 350 MPa. It has a large crushing ratio and a cubic particle after crushing. The size of the discharge material can be adjusted, and the crushing specifications are diversified.
The hydraulic fixed cone crusher is suitable for the crushing of raw materials in the metallurgy, construction, road construction, chemical, and silicate industries. According to the different crushing principle and different product particle size, the hydraulic fixed cone crusher machine can be divided into many models, namely, single-cylinder hydraulic cone crusher, full hydraulic cone crusher, etc.
The cone crusher has a large crushing ratio, high efficiency, low energy consumption, and uniform product size. It is suitable for crushing medium and fine ores and rocks. HXJQ hydraulic cone crusher machine is developed on the basis of digesting and absorbing various types of cone crushers with international advanced level in various countries. It is clearly different in design from the structure of a conventional spring cone crusher and concentrates on the main advantages of the various types of cone crushers known to date.
Whether it is a fixed crusher or portable rock crusher, it has its own advantages. The portable crushing plant can reduce the production cost more effectively for customers. It is an economical and integrated choice, so it is more and more popular among users, and its performance advantage can be fully demonstrated in actual production.
In addition, the special design concept completely eliminates the obstacles of crushing sites, complicated basic configuration, truly providing customers with efficient and low-cost hardware facilities for project operation. If you want to build a complete crushing line, then a portable rock crusher machine is a good choice, which saves time, money and effort. While the fixed crusher is suitable for handling materials with high hardness and large block size.
Regarding the price of the two types of stone crushing machines, the output of different types of crushers is different, so the price will, of course, be different. Therefore, in order to obtain a quotation, it is necessary to select the most suitable crusher according to the production needs of each customer and the crushing materials. Contact us, we will design the most suitable stone crushing machine for you
how to prolong the service life of a portable rock crusher? - hongxing machinery
What impacts the service life of a portable rock crusher? Basically there are several sectors including operations, maintenance and equipment process which is crucial to the quality and service life of a machine, all of which should be known in details.
If the main parts of the portable rock crusher such as frame, lining, hammer, bearing, etc. are made of material with poor quality or bad wear-resistance property, it will affect the whole uptime. Feeding material with too much hardness would causes severe abrasion, intensive pressure even damage of wear parts due to low heat treatment process and material hardness beyond wear resistance during the reducing process. However, according to statistics, frequent damage of components not only reduce the service but cause malfunctions. So, material with excellent wear-resistance creates high-quality parts, reducing the damage rate, prolonging the machine life service when undertaking the same degree of wear. In a word, what kind of material you choose decides how long you can use it, efficiency and operation costs.
Taking a portable jaw crusher as an example, parts including frame, working parts, transmission parts, adjusting device, safety device and lubrication system are indispensable to the machine but having different importance for some determines the operation while others not. Here are more details about necessary parts that should be known.
Frame: usually a portable jaw crusher is divided into two types integrated frame and assembled one. A lot of small and medium sized equipment utilize integrated frame being welded or cast by steel while large sized one characterized by difficult transportation and process are installed assembled frame and the latter is made up of a number of cast iron or welded parts joined by bolts. So, the material of frame has direct relationship with equipment quality.
Working part: another important part is crushing cavity composed of stationary jaw and mobile jaw. Being directly involved in crushing operation, the lining panel must process high quality and good material. Recently, the surface of the liner is usually cast into a wavy and triangular shape. In addition, with the development of modern high-tech R&D and application of computers, the design of liner has broken the bottleneck restrictions on the basis of combination of traditional experiments and optimized design of computer, finally making great progress in crushing results.
Transmission part: being composed of eccentric shaft, linkage coupled with before and after thrust, transmission part is also vital to aportable rock crusher when it comes to whether sequential operation can be made. When the motor is started, the eccentric shaft rotates, thus driving the linkage to move up and down to push thrust plate.
Honestly, when purchasing aportable rock crusher, please do not stare at cheap price only, and it cannot provide you an ideal machine that you want. The quality of components decides the quality of the whole machine, which means parts with good material make up of a tough machine with long-term service life.
After the selection of the material with good wear resistance, the process of assembling the different parts ofaportable rock crusher is also an important factor affecting its service life. Perfect process will enhance the performance, create robust and high-quality equipment thus prolong the life service in production. On the contrary, bad process such as unreasonable gap between the parts would lead to terrible machability during the operation, severely affecting the service life.
As an crucial equipment in reducing operation, a portable rock crusher under the proper use can maximize its advantage and efficiency of continuous processes, reducing transport distances and costs. To a portable crusher plant, the layout and way to move should be aimed at lowest process costs and take impact on the production efficiency into full consideration. A portable rock crushing plant is generally applied in the open pit to reduce the distance to the single bucket excavator, moving with mining schedule. Some portable plants need to move once at the range of 3-6 months, others maybe need 1-3 years to do a movement, which shows theperiod of displacement is very important to decide frame structure of a portable plant.
When it comes to short time period, it is necessary to consider the situation where the overall structure is convenient to be frequently moved and can adapt to the geographical environment. Generally, the portable crushing plant with short-period movement will utilize the trestle type, relying on the stripping step in addition to simple retaining wall and a steel structure trestle without an expensive concrete retaining wall. Costs can also be reduced by means of natural slopes to set up natural hopper.
For long-term shifting, whether the overall stability is suitable for long-term placement without affecting the performance of the reducing plant is what we should think about. The medium and long-term mobile equipment often needs to design a huge retaining wall with reinforced concrete structure, taking into account the load of the truck, the bearing capacity of the wall and the proper position of the hopper in the retaining wall.
Due to modular design adopted by a portable rock crusher, the time of displacement is greatly lowered and more flexible compared to fixed crusher. In order to lighten the weight of the frame and improve the fatigue resistance of the walking crawler, the important parts and components are made of fine-grained special alloy such as Mn13, Mn13Cr2, chrome alloy and rare earth wear-resistant steel. The core equipment crusher adopts double-geared roller crusher which reduce the weight and size, further improving the capacity. Tracked crusher according to different way of arrangement is divided into transverse and vertical arrangements which can be converted according to the process requirements.
Despite simple and reliable equipment structure, it is necessary to go on every step strictly according to operation regulations. Lack of experiences and carelessness cause improper use and maintenance, thus leading to bad performance. What should be took into account are whether the entire crushing chamber is filled with material instead of only in feeding space between the fixed and moving cone liners; whether the lubricating oil is added on time; whether the roots, wires, etc. in the cavity are cleaned in time. All those details easily neglected in work will inevitably accelerate the wear of the parts and block the oil flow, which accumulating to a certain extent will lead to major economic losses, service life reduction even equipment broken.
