rock crushers at kellyco | gold prospecting equipment
In order to crush rocks and extract gold, you will need the right equipment that can achieve this quickly and efficiently. That being said, utilizing rock crushers will help prevent you from missing the opportunity of hitting paydirt. Portable rock crushers will change the way you prospect for gold and with several options available, making sure that you select the correct product will be invaluable.
The term itself is pretty self-explanatory. These machines are designed to crush any type of stone from quartz to limestone and everything in between. How much is able to be processed per hour will depend on the model you purchase.
The intention of small rock crushers, such as those we have here at Kellyco, is to allow you to extract more gold instead of leaving any paydirt behind. The amount of gold that can be contained within rocks in areas you didnt know were there may surprise you. However, without a rock crusher in your arsenal, you will never be aware of what was left behind.
Portable rock crushers use a very simple approach, power. With various sized engines available depending on the model, these machines are designed to take small rocks and, thanks to a huge amount of pressure and power, crush them down and allow you to process them through your sluice box.
The aim of any small rock crusher for sale is to be able to break that rock down into a fine powder. In doing so, it will be able to pass through a classifier before going through the sluice box and any gold can then be separated. Even relatively small pieces of rock that are left intact could lead to you missing out on some gold, and when you know you have hit paydirt then you hardly want to leave anything behind.
Most models, including the Keene G-Force rock crusher, will use a hopper box with gravity to move the rocks through the crusher. The rock is fed into the hopper box and then moves into the central compartment of the crusher. A huge amount of force effectively smashes the rock at high speed and the greater the force then the finer the powder. With that in mind, the power of the engine contained within the rock crusher will be important.
With several options available, knowing which are the best rock crushers for sale will make your job of identifying the right product for you easier. Of course, budget may play a part but Kellyco does have a number of small portable rock crushers for sale across a wide price range.
There are several key points to consider when looking at purchasing a portable rock crusher. First, there is the volume of rock that can process for up to an hour. With some capable of producing over 2 tons of powder, also known as grind, this should be more than adequate for the majority of treasure hunters.
Another point to remember is the size of rock that the crusher can handle. These kinds of rock crushers for sale are not designed to take large boulders and break them down on an industrial scale. Instead, we are talking about rocks that are around one inch in size that can be effectively smashed in seconds. Once again, we recommend that you check the maximum size that the model you are looking at can take before making your purchase.
The best rock crushers for sale will contain a large hopper box, be capable of crushing a substantial amount of rock in one hour, and break things down into an easy to manage powder. As long as those points are met, then you should not have any problem extracting as much gold as possible from your expedition.
There are several additional features that deserve to be mentioned with a rock crusher. For example, you need to examine how a particular model is powered. With both gas and electric available as options, it should be easy for you to get things started. As a side-note, the gas version is often regarded as being cheaper to operate. Also, we have to think about transportation. These machines are not the lightest around which is why there are lighter models, such as the Keene trailer mounted crusher, on the market. This does make it easier to get to those more remote areas that you may wish to venture to on your expeditions.
You may wish to consider looking at the process that the rock crusher uses in order to deliver the powder. Different models may put the rock through various processes with each stage resulting in something even finer than before.
Finally, there has to be the question of replacing parts even when you are out there in the wild. Cleaning the machine and clearing it of debris is important or it may result in becoming clogged. However, models that have been manufactured by Keene will all be easy to adjust and maintain so this shouldnt be a problem.

It includes jaw crusher, impact crusher, cone crusher, vibrating screen and other combination type, which can be transported wholly-assembled and apart.
Senya Tech offer a wide range of mobile rock crushers, scalpers&screeners, both tracked and wheeled, including jaw, cone&impact crushers.Mobile crushing and screening equipments developed by Senya are used widely in mining, crushing, construction waste recycling fields etc.
The size requirement of the primary rock crusher is a function of grizzly openings, ore chute configuration, required throughput, ore moisture, and other factors. Usually, primary crushers are sized by the ability to accept the largest expected ore fragment. Jaw crushers are usually preferred as primary crushers in small installations due to the inherent mechanical simplicity and ease of operation of these machines. Additionally, jaw crushers wearing parts are relatively uncomplicated castings and tend to cost less per unit weight of metal than more complicated gyratory crusher castings. The primary crusher must be designed so that adequate surge capacity is present beneath the crusher. An ore stockpile after primary crushing is desirable but is not always possible to include in a compact design.
Many times the single heaviest equipment item in the entire plant is the primary crusher mainframe. The ability to transport the crusher main frame sometimes limits crusher size, particularly in remote locations having limited accessibility.
In a smaller installation, the crushing plant should be designed with the minimum number of required equipment items. Usually, a crushing plant that can process 1000s of metric tons per operating day will consist of a single primary crusher, a single screen, a single secondary cone crusher, and associated conveyor belts. The discharge from both primary and secondary crushers is directed to the screen. Screen oversize serves as feed to the secondary crusher while screen undersize is the finished product. For throughputs of 500 to 1,000 metric tons per operating day (usually 2 shifts), a closed circuit tertiary cone crusher is usually added to the crushing circuit outlined above. This approach, with the addition of a duplicate screen associated with the tertiary cone crusher, has proven to be effective even on ores having relatively high moisture contents. Provided screen decks are correctly selected, the moist fine material in the incoming ore tends to be removed in the screening stages and therefore does not enter into subsequent crushing units.
All crusher cavities and major ore transfer points should be equipped with a jib-type crane or hydraulic rock tongs to facilitate the removal of chokes. In addition, secondary crushers must be protected from tramp iron by suspended magnets or magnetic head pulleys. The location of these magnets should be such that recycling of magnetic material back into the system is not possible.
Crushing plants for the tonnages indicated may be considered to be standardized. It is not prudent to spend money researching crusher abrasion indices or determining operating kilowatt consumptions for the required particle size reduction in a proposed small crushing plant. Crushing installations usually are operated to produce the required mill tonnage at a specified size distribution under conditions of varying ore hardness by the variation of the number of operating hours per day. It is normal practice to generously size a small crushing plant so that the daily design crushing tonnage can be produced in one, or at most two, operating shifts per working day.
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.

Eastman is a typical direct selling enterprise with green and standardized production plants. All the delivery of the equipment will be completed within the delivery period signed by the contract to ensure the smooth commissioning of the equipment.
Rock crushers have a wide range of suitable material to choose from, whether its soft or hard, or even very hard, rock crushers can reduce those large rocks into smaller rocks, gravel, or even rock dust.Here are some typical materials that break or compress by industry crushers, such as Granite, quartz stone, river pebble, limestone, calcite, concrete, dolomite, iron ore, silicon ore, basalt and other mines, rocks and slag.
Understanding the stages of crushing process and the types of crushers that best fit each stage can simplifies your equipment selection. Each type of crusher is different and used to achieve a certain end result.
Similarly, a certain output is expected at the end of each crushing stage for the next phase of the process. Aggregate producers who pair the correct crusher to the correct stage will be the most efficient and, in turn, the most profitable.
A jaw crusher is a compression type of crusher. Material is reduced by squeezing the feed material between a moving piece of steel and a stationary piece. The discharge size is controlled by the setting or the space between those two pieces of steel. The tighter the setting, the smaller the output size and the lower the throughput capacity.
As a compression crusher, jaw crushers generally produce the coarsest material because they break the rock by the natural inherent lines of weakness. Jaw crushers are an excellent primary crusher when used to prepare rock for subsequent processing stages.
Although the chamber is round in shape, the moving piece of steel is not meant to rotate. Instead, a wedge is driven around to create compression on one side of the chamber and discharge opening on the opposite side. Cone crushers are used in secondary and tertiary roles as an alternative to impact crushers when shape is an important requirement, but the proportion of fines produced needs to be minimized.
An impact crusher uses mass and velocity to break down feed material. First, the feed material is reduced as it enters the crusher with the rotating blow bars or hammers in the rotor. The secondary breakage occurs as the material is accelerated into the stationary aprons or breaker plates.
Impact crushers tend to be used where shape is a critical requirement and the feed material is not very abrasive. The crushing action of an impact crusher breaks a rock along natural cleavage planes, giving rise to better product quality in terms of shape.
Most aggregate producers are well acquainted with the selection of crushing equipment and know it is possible to select a piece of equipment based solely on spec sheets and gradation calculations. Still, theoretical conclusions must always be weighed against practical experience regarding the material at hand and of the operational, maintenance and economical aspects of different solutions.
The duty of the primary crusher is, above all, to make it possible to transport material on a conveyor belt. In most aggregate crushing plants, primary crushing is carried out in a jaw crusher, although a gyratory primary crusher may be used. If material is easily crushed and not excessively abrasive, an impact breaker could also be the best choice.
The most important characteristics of a primary crusher are the capacity and the ability to accept raw material without blockages. A large primary crusher is more expensive to purchase than a smaller machine. For this reason, investment cost calculations for primary crushers are weighed against the costs of blasting raw material to a smaller size.
A pit-portable primary crusher can be an economically sound solution in cases where the producer is crushing at the quarry face. In modern plants, it is often advantageous to use a moveable primary crusher so it can follow the movement of the face where raw material is extracted.
The purpose of intermediate crushing is to produce various coarser fractions or to prepare material for final crushing. If the intermediate crusher is used to make railway ballast, product quality is important.
In other cases, there are normally no quality requirements, although the product must be suitable for fine crushing. In most cases, the objective is to obtain the greatest possible reduction at the lowest possible cost.
In most cases, the fine crushing and cubicization functions are combined in a single crushing stage. The selection of a crusher for tertiary crushing calls for both practical experience and theoretical know-how. This is where producers should be sure to call in an experienced applications specialist to make sure a system is properly engineered.
