Mobile jaw crusher is the latest stone crusher machine and mainly used for metallurgy, chemical engineering, building materials and other industries which usually require moving work, especially the construction of high-speed way, railway. Customers can adopt several configurations according to different demands of raw materials, working scales and finished products.

The mobile jaw crusher plant greatly expands the application of coarse crushing, and it combines primary crusher with the secondary crusher (cone crusher or others), which has finer crushing size. The design principle of mobile jaw crusher is to stand in the customer's position, eliminate the obstacles of working sites and surroundings, and offer the facilities with the features of high efficiency and low costs.

The main equipment of mobile jaw crusher is fixed frame, jaw crusher, feeding machine, vibrating screen, conveyor, motor and control cabinet, etc. The outstanding feature of the equipment is environmental protection.

From the aspect of feeding inlet--engineers found that when conveyor transferred materials to the inlet of jaw crusher, the dust will rise when materials falling. And this is the main reason for polluting working sites.

The mobile jaw crusher optimizes and upgrades the crushing cavity of the jaw crusher, strengthening its tightness, so that the dust produced in the operation can stay in the crushing cavity and be discharged with the finished products. The dust can be discharged from the dust collector by sorting at the discharge port to realize the environmental protection of the mobile jaw crusher.

When mentioning the jaw crusher used for the primary crushing, the insiders are very familiar with it. Thus, the mobile jaw crusher refers to the jaw crusher that is loaded by the mobile crushing plant. So compared with the fixed jaw crusher, what are the outstanding features and performances of mobile one?

It is not difficult to see through the table that the fixed jaw crusher has high requirements on the site and requires centralized feeding. Moreover, the fixed one and other crushing equipment are combined to form an integrated fixed crushing station which is a standard and upgraded working production line with complicated installation and not suitable for crushing requirements with strong mobility. But the mobile jaw crusher is relatively simple in structure, reasonable in installation, so the transportation is more flexible and convenient. In addition, mobile jaw crusher also has many other advantages and features.

This environmentally friendly mobile Jaw crusher has a compact structure and is fully enclosed. It is also equipped with anti-noise and dust-removing devices to ensure the surrounding residents to be free from noise interference and the customers to achieve the environmental protection standards.

As a professional manufacturer of mining equipment, HXJQ has more than 40 years of manufacturing experience with the sales strategy of low profit and high turnover to help customers reduce the investment cost as much as possible.

The products of HXJQ are mainly sold to Southeast Asia, Africa and other places, and there are distribution stations in each port. The machine can be sent to your working site within two weeks after placing an order. There are also professional engineers to explain the installation skills for you.

Construction waste has its characteristics as follows: diverse materials, mixed piles, different hardness, and the most important point is scattered distribution. To make full use of construction waste, a series of steps such as crushing and screening are required, and since construction waste is distributed in different places, it is better if the operations can be carried out hastily. At this time, the mobile crushing plant is the best choice for crushing construction waste!

After crushing, the construction waste is sorted, removed and crushed, and most of them can be reused as renewable resources, such as scrap steel, scrap iron wire, waste wire and various scrap steel parts. And then they are concentrated and re-heated for reproducing various kinds of steels; the bricks, stones, concrete and other scraps can be crushed and used for sand, plaster, concrete cushion, etc.

With the advancement of technology and the increase in customer demand, mobile jaw crushers are favored by more and more customers, especially in the sand making industry with strong material mobility. Due to the large volume of the rock after mining, it is not ideal to use the secondary crushing machinery to crush it directly. Therefore, the feeder is required to feed the stone evenly into the feed port of the mobile jaw crusher for coarse crushing. And then, the larger size stones are transported by a conveyor to a sand maker for fine crushing.

There are many kinds of raw materials for sand making. Combined with the operating principle of the stone sand maker, it can be known that only when the processing raw materials are broken to the specified fineness and then crushed by the sand maker for a uniform particle size, so on the sand making line, the mobile jaw crusher will be used for primary crushing, and the produced large-sized stones are transported by the belt conveyor for deep crushing to produce high-performance sand.

The construction of roads and bridges is the top priority of the country's infrastructure construction. The country's huge investment in the construction of roads, bridges and railways has supported the increase of the national economy. Due to the transportation distance, transportation mode, reserves and quality of natural sand and stone material are difficult to meet the requirements, more artificial sandstone materials are used. And the stone material production line technology has been developed.

The construction of road and bridge requires high-quality sand and gravel aggregates, while high-quality sandstone aggregates need to use high-quality crushers and sand maker. The stable and reliable complete crushing equipment is related to the quality and engineering effect of the whole project. The selection of equipment for the production line affects the quality of the product and the investment in the processing system. Moreover, due to the fixed site selection and long route of the road construction, the required materials are huge and inconvenient to transport, which means that the mobile crushing is the best choice for road building.

In October 2018, a customer from Nepal contacted HXJQ customer service, hoping that we could provide a mobile crushing plant for crushing construction waste. The customer's requirement is a feed size of 150-300 mm and requires a capacity of 30-50 t/h. According to the data provided by the customer and his specific requirements, the technical manager quickly contacted him and designed a construction waste mobile crushing plant suitable for him.

After many times of communication and comparison, the customer finally chose HXJQ to provide a set of equipment. The selection is HX2575E46-3S123PYB900M model, including wheeled movable crushing plant, PE-400600 jaw crusher (processing capacity: 16-64t/h), PYB800 cone crusher (processing capacity: 35-80 t/h), GZD7502500 vibrating feeder (processing capacity: 100-130 t/h), 3YZS1237 vibrating screen, transport length, width and height are 15200 mm, 2900 mm, 4350 mm respectively.

At present, the customer's mobile crushing plant has been put into use for several months. Through repeated visits and customer's feedback, the mobile crushing production line designed by HXJQ runs stably, with outstanding performance in terms of material size, product shape and quality, which is a great satisfaction for this customer.

Based on these requirements and data, our technical manager has designed a detailed, applicable mobile crushing line. It includes the mobile crushing plant of the HX853E57 for primary crushing and the HX3S185GYS300 mobile crushing plant for secondary crushing and screening. The specific configuration and data are as follows:

So far, the mobile crushing plant has been serving customers for more than one year. In the past year, once the customer has any technical problems, HXJQ will provide after-sales service and guidance in time, and go to the scene to solve problems for customers promptly.

So the customer can't help but feel:"It turns out that HXJQ is the right choice. The perfect after-sales and high-quality crushing equipment have removed my worries. And I will concentrate on expanding production and look forward to working with HXJQ for long-term cooperation."

With the continuous development of science and technology, mobile jaw crusher technology in China continues to surpass the foreign technology, and the domestic market competition is fierce, and the mobile jaw crusher is much expensive. Therefore, the following matters should be paid attention when selecting the models of mobile jaw crusher.

1. Have a certain understanding of the required equipment model, have a general budget for the cost, and choose a more accurate equipment model, which is more conducive to improving production efficiency and saving unnecessary expenses.

2. Have a certain understanding of the raw materials of the production. Different processing of raw materials and different manufacturing materials of each part will lead to different costs. If the material quality is better, the price will certainly be more expensive.

However, if the equipment does not match with the processing of raw material, it not only affects the production efficiency but also wastes the cost. Users about how to avoid unscientific configuration must pay attention to the strength and credibility of manufacturers.

As a Chinese manufacturer of mobile jaw crusher, HXJQ has been adhering to the responsible attitude for each product and every user and dedicated to serving users. If you want to buy a mobile jaw crusher, HXJQ will be the best choice.

high-efficiency jaw crusher

high-efficiency jaw crusher

SUBSTANCE: proposed jar crusher is intended for crushing of initial material in mining and construction. This crusher comprises bed (7), fixed jaw (1) and moving jaw (2), moving jaw suspension hinge pin (14), spacer boards (5) and (6), con-rod (3), hinges between con-rod and spacer boards, flywheel (4), camshaft (8), V-belt transmission (13) and motor (12). Moving jaw has recess (15). Jaws are bent at lower part at 145 towards fixed jaw. Hinge pin at lower part thrusts by bearings against bed side walls. Spacer boards are fitted on con-rod at its top part by vortex of spacing angle directed upward. At con-rod downward travel impact if developed by the weight of spacer boards, con-rod and extra weight (19).

Jaw crushers provide maximum crushing pressure on the crushed material compared with other crushers, so they are indispensable for crushing solid, large, abrasive materials. As a result, processing factories for the production of crushed stone and cement jaw crusher is installed in the head manufacturing process, the first crushing stage where you need the most high crushing pressure. Therefore, stable operation of jaw crushers depends on the performance of the whole production.

Jaw crusher with a simple swing of the movable cheeks are typical, as all domestic and foreign crusher with a simple motion of the jaw have the same design and differ only in size and some unimportant changes in the solution of individual nodes [1]. The working principle is similar: when the rotation of the eccentric shaft rod receives a reciprocating motion in the vertical plane, which by the spacer plates is transmitted to the mobile cheek. In this case the angle between the spacer plates is constantly changing, let's call it " the m of spreading plates.

Due to the fact that well-known jaw crusher have a low degree of fragmentation within 4-6, manufacturing, to obtain the necessary fineness crushing, used three - and even chetyrehstvolnym circuit crushing. This dramatically increases the cost of the crushing process and requires large power consumption.

It is known that in order to simplify mnogostadiinykh schemes crushing and reducing the cost of the crushing process design "Jaw crusher with high crushing" (patent RF 2458740, publ. bull. No. 23, 2012).

Analytical research and testing laboratory sample of this crusher is installed in the upper chamber of the crusher, as a result of installing the spacer plates for the top corner strutted down may not be enough crushing pressure for crushing high strength materials. This is because the engine, creating pressure between the crushing plates, performs the additional load required to lift up the weight of the rod and spacer plates. (In the crusher SDP - 1521 the mass of the connecting rod and spacer plates is about 18 tons). That is, there is untargeted energy consumption, reducing the crushing pressure. Therefore, in order to create enough crushing pressure for crushing high strength materials will need to be powerfully increase the t of the electric motor, what it is not - desirable.

To prevent this proposed design "Jaw crusher impact-crushing action with high degree of fragmentation, in which the mass of the connecting rod and spacer plates create an additional impact, contributing to fragmentation by way of crushing high strength materials, without increasing power of the electric motor.

According to the invention this objective is achieved in that the spacer plate in the crusher is installed on the rod above the top corner strutted up (unlike the design of the crusher according to the patent of Russian Federation 2458740), and the top of the rod (if necessary) can be attached more weight, contributing to an increase of the impact force at the time of crushing.

The extra load on the rod will increase the total mass of the crusher, as the load will be compensated by reducing the mass of the flywheel. In the construction of jaw crusher with high crushing no idling, therefore, does not require large mass of the flywheel, smoothing peak loads on the motor.

The invention is illustrated in the drawing (Fig.). We offer jaw crusher impact-crushing action consists of a moveable jaw 1, the movable cheek 2, rod 3, the flywheel 4, the spacer plates 5 and 6, frame 7, the eccentric shaft 8, node swivel spacer plate with movable cheek 9, node swivel spacer plate with the frame 10, node swivel with spacer plates 11, a motor 12, a V-belt transmission 13, the axis of suspension of the movable cheeks 14, additional cargo 19, bolts - 20.

Both crushing cheeks suspension axis of the movable cheeks are bending towards the moveable jaw at an angle of 145 from the vertical. Axle suspension parts cheek on the top and the bottom, and the cheeks form its enclosures top and bottom of the crushing chamber. Mobile jaw 2, opposite the axis of the suspension 14 has on the inner side of the recess 15, is necessary to prevent zabivac crusher at the moment of transition of the material from the upper chamber to the lower chamber.

The fixed jaw is fixed in the frame of the crusher vertically. The mobile jaw is suspended on the axis 14, which is fixed in bearings mounted in the side walls of the frame of the crusher, at the height of the bottom 1/3 of its length.

The source material is fed through the loading hole 16 in the upper chamber crushing. Mobile jaw 2 is contained in D. iunie, receiving the force from the eccentric mechanism, which includes the flywheel 4, the connecting rod 3 and the spacer plates 5 and 6. The flywheel receives rotary motion from the electric motor 12 V-belt 13.

When the movement of the connecting rod 3 upwards, the angle between the spacer plates 5 and 6 is reduced, and the spacer plate 5 with a large force pulls the upper end of the movable cheeks from stationary. At this point, the lower end of the movable cheek closer to the stationary cheek and produces fine crushing in the lower chamber by way of crushing material. When the crushing force is maximum, as well as used the lever formed by the length of the movable cheek above the axis of suspension. More than this length, the greater will be created pressure on the crushed material.

It is an advantage of the crusher, which allows to overcome the scale factor. The essence of the scale factor [2] is that the specific strength pieces with their reduction increases. As well as in the lower chamber the size of the pieces will be less than about 5 times, than at the top, at the bottom of the camera you want to create more crushing pressure than the upper chamber.

When the movement of the connecting rod 3 down, the angle between the spacer plates is increased to 170, and the rod 4 creates pressure on the spacer plates 5 and 6. Spacer plate 6 rests against a stationary article is Nina and cannot move in the horizontal plane. Spacer plate 5 rests on the upper end of the movable cheek 2 and moving in a horizontal plane in the direction of the fixed cheeks with great effort, brings the movable cheek with a fixed. At the time of convergence crushing cheeks in the upper chamber is a large crushing of the material by way of crushing. At this point in the lower chamber is discharging crushed material as the lower end of the movable cheeks removed from the still.

A distinctive feature of this crusher from all known constructions of jaw crushers is to install the spacer plates in the rod for the top corner strutted up. This installation of spacer plates increases create a crushing pressure in the upper chamber, as it is created not only by the energy of the electric motor, but falling weight down weight rod and spacer plates (large jaw crushers this mass is equal to about 18 tons).

When you drop weight 18 tons, down goes the extra kick that creates an instant boost, which is added to the crushing pressure and increases the crushing efficiency without increasing power of the electric motor.

The mechanism of falling down cargo in the proposed crusher is similar to the action of the drop weight in the design of the diesel hammer, driving reinforced concrete piles into the soil during construction of the foundations the clients. In the diesel hammer is used a weight of about 1 ton, which does a lot of work, hammering piles, therefore, the use of this mechanism in the proposed crusher, where the cargo weight is 18 tons, will undoubtedly increase the efficiency of the crushing process. This is confirmed by analytical calculations, according to which the crushing force upon impact increases by approximately three times.

In the proposed crusher compression of the material in the upper chamber during movement of the connecting rod and spacer plates down, and compression of material in the lower chamber during the stroke of the connecting rod and plate up. Thus, in the first case the weight of the parts will be added to the crushing force, and in the second case, on the contrary, be deducted from it. But this will not affect the operation of the crusher, because the compression in the lower chamber is significantly higher than at the top, and it will always be enough for crushing the material in the lower chamber.

The upper chamber in the proposed crusher has similarities with the known design of the crusher according to the scheme Dodge [1], where the axis of suspension of the movable cheek installed at the bottom. It is known that the crusher Dodge has not found wide application in industry, due to the lack of progress rolling cheeks in the lower part of the crushing chamber, which leads to frequent zabivka crusher.

The design of the offered crushers are significantly different is raised from the scheme Dodge those what mobile jaw has significant move higher deepening it, which is ensured by the crushing of the material to the required size at its transition from the upper chamber to the lower chamber. Therefore, in the proposed crusher in this place driving will be excluded. During this travel of the movable cheeks in the lower part of the upper chamber may be increased by increasing the radius of the recess B, but this is only possible in the manufacture of (casting) rolling cheeks.

Thus, offer jaw crusher is not idle and has a degree of fragmentation in 5 times greater compared to typical jaw crusher with a simple swing of the movable cheeks. Install the connecting rod and spacer plates over the eccentric shaft provides the principle of the lever in both chambers for maximum crushing pressure on the crushed material. In the lower chamber, the lever action is created by the length of the movable cheek 2 above the axis of the suspension 14. At the same time, the greater will be the length of the movable cheeks, the more force will be created for crushing crushed material. In the upper chamber, the lever action is created by a connecting rod 3 and the spacer plate 5, and the greater will be the length of the spacer plate 5, the more force will be created for crushing material.

The principal difference in the construction of the proposed crusher from all known constructions of SECO what's crusher is to install the spacer plates in the rod for the top corner strutted up consequently, an additional effect of crushing when you drop down the weight of the rod and spacer plates, which create its mass strike on the crushed material.

Jaw crusher impact-crushing action with high degree of fragmentation, with a frame, a stationary and a movable cheeks, deepening at last, curved at the bottom part at an angle of 145 in the direction of the fixed cheeks, flywheel, axle articulated suspension of the movable cheek, in the bottom part supported by bearings on the side walls of the frame, eccentric shaft, connecting rod, spacer plate, V-belts, motor, articulated joints connecting rod with spacer plates, characterized in that the spacer plate mounted on the rod in the upper part of the apex angle of spreading upwards, resulting in movement of the rod down creates a crushing blow to the material mass falling spacer plates, connecting rod, to anitelea cargo that increases the crushing efficiency is very durable and abrasive materials without increasing the power of the motor.

The following example demonstrates a method of selecting the components of an aggregate plant. Good component efficiency and part performance pre-evaluation is essential to a solid design. The aggregate production requires the consideration of several crushers, feeders and screens. This is not intended to be a typical situation, though it does involve common crusher and screen units often used in aggregate plants.

Quarry rock of 12 in. maximum size is to be handled in a two-stage crusher plant at the rate of 70 tons per hour. The maximum size of output is to be 1 in., and separation of materials over 1 in. size and the minus 1 in. in the output is required. Select a jaw crusher like those included in this table.

The screens to be considered are a 1-in. screen with an estimated capacity of 2.7 tph/sq ft and a 1-in. screen with a capacity of 2.1 tph/sq ft. The solution will include the selection of adequate and economical crushers for the two stages and the sizes of screens between them and below the secondary stage.

For the primary crusher a jaw crusher will probably be most economical. A jaw crusher, like 2036 in the Jaw Crusher Table here above, would be able to take the maximum 12 in. size quarry stone but it would not have the required 70 tph capacity needed. To have the needed capacity a jaw crusher like the 2042 or 2436 sizeswill have to be selected overloading the secondary crusher.

A grid chart or curve for the selected crusher shows that, for a 2-in. setting, 54% of the material will pass a 1-in. screen, or 46% will be retained (this is like Jaw Crusher capacity table abovewhere 48% passes a 1 in. screen). The 46% of 70 tph gives the 32 tph fed to the secondary crusher shown in Figure below as a roll crusher.

A twin-roll crusher is selected, like those given inthe Roll Crusher capacityTable above, to serve as the reduction crusher. The smallest, 24 x 16 roll crusher shown in theRoll Crusher capacity Table above has enough capacity with a setting of 1 in. but the maximum size feed will be too large, that is, the stage of reduction is not large enough. The maximum size of feed coming from the discharge of the primary crusher with a setting of 2 is about 3 in. as may be found in this Table.

Considering a 30-in. diameter roll crusher the maximum size particle that can be nipped with the roll crusher set at 1 in. according to this Equation is F = 0.085(15) + 1.0 = 2.28 in. <3 in. feed. It will take larger than a 40-in. diameter roll crusher. A better solution would be to use a larger jaw crusher set at 1 in., then a roll crusher from the Roll Crusher capacityTable above could be used. If the output of this crushing process should have less material of the +1-in. size, the larger crusher could be operated with a closed circuit. That is, the oversize in the output could be recirculated through the roll crusher without exceeding the rated capacity of the crusher. Then all material leaving that crusher with a 1-in. setting would be of a minus 1-in. size.

Another possible solution to this problem would be to use a gyratory crusher for the primary crushing stage. A gyratory like Telsmith model1110 could be set at 1 in. in an open circuit with a capacity for 260 tph. The maximum size of stone in the output is estimated to be approximately 2 1/8 in. Then all the output from the primary crusher could be nipped by a 40 in. diameter twin-roll crusher with a 1-in. setting according to the Roll Crusher capacityTable above. The specifications and manufactured limitations, rather than economy, generally govern the selection of crushers.

To find the required areas of screen, the rate of feed of material as well as gradation of the feed must be known. The 1-in. screen under the jaw crusher is the top deckno deck correction factor will be necessary. Therefore, the 1-in. screen will need to be at least 70/2.7 = 29.9 sq ft in area. It must be at least 36 in. wide for an 18 x 36 jaw crusher. So a 4-ft by 8-ft screen would be acceptable. The 1-in. screen is a second deck for the 38 tph from the jaw crusher, so the deck correction factor is 0.90 and that screen capacity is 2.1 x 0.9 = 1.89 tph/sq ft.

The screen area needed under the jaw crusher is 38/1.89 = 20.1 sq ft. For the 1-in. screen below the roll crusher the capacity has no correction factor and the area needed is 32/2.1 = 15.2 sq ft. To handle the output from a 40 x 24 roll crusher the screen will have to be at least 24 in. wide. Perhaps it will be more effective to use one continuous screen of at least 20.1 + 15.2 = 35.3 sq ft. A 4-ft by 10-ft 1 in. screen should be satisfactory.
