the common questions of mobile crushing plant and corresponding solutions | hxjq

The mobile crushing plant is also known as a portable crushing plant and mobile crushing station, which is one of the most common mobile crushing equipment used in the process of crushing stone and making sand.

This article will answer all the questions of mobile crushing plants, hoping you can get help. For questions not covered in this article, you can also leave a message on the right or send us an email, we will answer you as soon as possible.

Mobile crushing plant is the most advanced crushing equipment than all other crushers, and it is very popular among investment enterprises and mine owners because it has good crushing performance, large capacity, and wide applications.

However, it should be noted that may the mobile crushing plant be not a good investment project for every crushing equipment purchaser. So what kind of crushing type is the mobile crushing plant suitable for?

The mobile crushing plant can not only carry various crushers and machine in several models (such as jaw crusher, cone crusher, impact cone crusher and sand making machine, etc), but also operate with other machines, which makes a large capacity.

For mobile crushing plant, it is called plant rather than machine for one reason that it is a combination of multiple devices, such as feeder, crusher, conveyor, screen, and other machines, and another reason that it has a high crushing efficiency so that it can satisfy large capacity requirement, that is if the materials is not fed timely or inadequately, the investment in mobile crushing plant is not cost-effective.

The mobile crushing plant can be divided into two types: wheeled type and crawler type, which is suitable for various mines. Especially the crawler-type mobile crushing plant adopts the track driven method, which makes transportation more convenient.

The mobile crushing plant adopts different crushing equipment, carrying on the independent mobile chassis with the short wheelbase and small turning radius so that it can move in different terrain freely.

For example, there are many rich mineral resources in many areas of Saudi Arabia, but various reasons such as topography will bring a lot of inconvenience to production and processing. Therefore, most customers of mine crushing investment in the country often choose a mobile crushing plant to get economic profits.

In addition, due to its high configuration and high technology, the mobile crushing plant is much more expensive than a jaw crusher or a cone crusher. Therefore, customers who want to buy a mobile crushing plant should have sufficient funds. In this way, the mobile crushing plant is more suitable for companies that are rich in processing materials and have sufficient investment funds.

Irregular vibration and vibration of the mobile crushing plant: there may be problems with the hammers. It is necessary to check timely and replace the hammer if necessary. It may also be problems with the bearing and gear coupling. It should be replaced in time to make the vibration smooth.

When the particles are too fine, may there are too many hammers or teeth in the jaws. Then they should be reduced in time. When the particles are too coarse, the hammer or jaw may be less, and they should be increased immediately. It is also possible that the conveyor belt is too loose or the voltage is insufficient. In this case, adjust the tightness of the conveyor belt, check the voltage power, and adjust to the appropriate voltage.

The shaft of the mobile crushing plant bears the full load of the machine. If the bearing temperature is too high, the oil may be insufficient, then you need to add proper amount of lubricating oil; if the lubricating oil is contaminated, you need to clean the bearing and then change the lubricating oil; if the bearing is damaged, you need to replace the bearing and lower the temperature.

If the mobile crushing plant has a poor lubrication effect, the parts that are easy to be worn are not replaced in time, and the maintenance is not perfect, all the above factors will lead to bad production. If the equipment is in trouble and maintenance is performed, the production will be reduced.

At present, the natural sand and gravel are in short supply. The production of artificial sand should be conducted immediately, and the source of artificial sand material is extensive, the production cycle is short, and the construction waste is processed into the sand as a substitute for natural sandstone.

Based on the wide distribution of construction waste and the mixed composition, it is generally suitable to use a mobile crushing and sieving machine. The waste mixture will be crushed by the mobile jaw crusher for the first time to form a mixture of uniform particle size, and then subjected to circular vibrating screen and air separation equipment to purify, screen, separate waste paper, plastic sheets and other debris.

The crushing process is mainly carried out by high-efficiency coarse or medium crushing. Generally, the mobile jaw crusher or the mobile impact crusher can be used, which can effectively crush all kinds of block materials and achieve semi-finished products with uniform particle size.

The sand-making part is generally conducted by the mobile sand making machine, and the sand-making and shaping are carried out simultaneously. The semi-finished products conveyed by the conveyor belt are finely crushed and super-finely crushed to make the finished product size and grain type required by the user.

Construction sand is mainly divided into coarse sand, medium sand and sand washing, coarse sand: average sand diameter is not less than 0.5 mm, medium sand: average sand diameter is 0.35 to 0.5 mm, fine sand: average sand diameter is 0.25 to 0.35mm. After the construction waste is processed by the mobile sand making machine, the above grading can be achieved.

Screening mainly plays a role of inspection, and the materials after crushing or sand making are inspected. The materials after reaching the standard are transported to the pile, and the materials that are not up to standard can be returned to the crushing chamber to re-crush.

At present, the crushing and sand treatment of construction waste has a most suitable machine--the construction waste mobile crushing plant. The mobile crushing plant covers the whole fixed production line and has the following advantages:

The equipment can be adjusted as needed. According to the process requirements, it can be flexibly matched with various crushing or sand making equipment. The mobile crushing machine is cost-effective and practical.

The environmental protection of this mobile crushing plant is strictly up to standard, which is a distinctive feature of it. Compared with the traditional fixed equipment, the mobile construction waste crushing plant can achieve green production and environmental protection.

The cost of 1 ton construction waste is very low or even negligible, and the price of finished materials is roughly between $10 to 18, which is equivalent to at least 8 to 9 dollars of gross profitper ton. In addition to the water and electricity costs, the daily gross profit can reach $3000, so it seems that construction waste sand making is a good investment industry.

mobile crushing and screening equipment for asphalt waste recycling - jxsc

Asphalt concrete pavement will inevitably have problems such as aging and cracking after a period of use. To repair, renovate or refurbish asphalt concrete pavement, the most commonly used treatment process is to use a milling machine to mill the asphalt concrete pavement to the upper layer, and then spread new asphalt concrete to repair or improve the original road surface.

Today, advocating green environmental protection and protection of primary resources will be of great significance for the use of milled asphalt concrete waste. After crushing and sieving the waste asphalt milling material, adding regenerated asphalt reducing agent, a small amount of new aggregates and asphalt mixture for pavement paving. This not only avoids the environmental pollution problems caused by the stacking and landfilling of waste asphalt milled materials, but also greatly reduces the use of asphalt and natural aggregates.

The customer purchased a set of crawler mobile crushing and screening production line for crushing and screening of asphalt milled material. The crushing and screening production line is mainly composed of a crawler moving impact crusher and a crawler moving inclined aggregate screening machine.

cone crusher | mine crushing equipment | jxsc mine

JXSC stone cone crusher machine is widely used in many sectors, such as mining, smelting, building materials, roads, railways, water conservancy, and chemical industries. Our stone crushers machine is suitable for primary, secondary and tertiary crushing. Cone crushers mainly divide into GP, HP and Symons series, compound, CS, HPC, sand, laboratory, propel cone, etc.

JXSC provides a high-quality rock crusher cone machine, like the brands of Mesto and Nordberg. We also have other series crushing machines, such as jaw crusher, impact crusher, hammer crushers and sand making machines.

The cone series crushers compress stone/rock mineral materials by squeezing force between the fixed shaft and moving shaft. Change the least gap between the two crushing shafts of the equipment can adjust the target particle size. When the wedge or eccentric rotator starts to work, compression comes into being within the cavity. As the rock materials move down, the chamber mouth becomes narrower, the material becomes smaller. The crushed materials discharge at the lowest of the machine once they through the chamber.

Cone crushing types of equipment are widely used in metal and non-metal mines, cement plants, sand and stone metallurgy and other industries. It is applicable to various ores and rocks with fine and fine Platt hardness 5~16, such as iron, granite, limestone, quartzite, etc. Its working principle is the same as that of the gyratory crusher, but stone crusher cone only for crushing medium or fine material. The uniformity of the discharge particle size of the medium and fine crushing operations is generally higher than that required for the coarse crushing operation. Therefore, there is must provides a parallel section at the lower part of the crushing chamber. At the same time, expediting the rotation speed so that the material is in the parallel zone and squeeze more.

The crushing of the medium-fine crushing operation is larger than coarse. Then the loose volume after the crushing has a large increase. In order to prevent the crushing chamber from causing clogging, it needs to increase the total discharge cross-section by increasing the diameter of the lower portion of the crushing cone. And without increasing the discharge opening to ensure the required discharge size.

The discharge opening of the cone crusher parts is small. It is easier to cause accidents if feeding the non-crushed material. Because the medium and fine crushing operations have strict requirements on the discharge size. It must adjust the discharge opening in time after the liner is worn, if not will damage the cone.

When the Simon-type spring safety rock crusher cone overload, the tapered housing forces the spring to compress and raise itself to increase the discharge opening, and discharge the non-crushed material. The adjustment of the discharge opening is via adjusting the sleeve. And the adjustment sleeve of the housing can be rotated to drive the housing to rise or fall by the thread on the outer circumference to change the size of the discharge opening. The secure and adjust of hydraulic cone crushers in the same way as a hydraulic gyratory crusher.

When the cone crusher is working, the rotation of the motor rotates by a belt pulley or a coupling. Some drive shaft and cone portion rotates under the urging of the eccentric sleeve. Therefore, the broken wall of the crushing cone is close to and sometimes leaves the surface of the rolling wall fixed on the adjusting sleeve. Then the ore is continuously subjected to impact, pressing and bending in the crushing chamber to realize the crushing of the ore. The motor drives the eccentric sleeve to rotate by the bevel gear, the crushing cone rotates. The crushing cone is close to and then leaves the fixed cone to complete the crushing and discharging. The joint between the support sleeve and the frame body is pressed by the spring. When the crusher falls into a non-breakable object such as a metal block. The spring is compressed and deformed to discharge foreign matter. Therefore achieving insurance and preventing damage to the machine.

When the tertiary cone crushers pass through the crushing chamber or the machine overload for some reason. The cone crusher spring insurance system realizes the insurance, and the discharge port increases. The foreign matter is discharged from the crushing chamber of the cone crusher. If the foreign matter is stuck in the ore, it can uses the clearing system to continues increase the output. The foreign matters discharge out. Under the action of the spring, the cone crush machine automatically resets the discharge port, and resumes normal operation. The surface of the crushing chamber cover with a wear-resistant high manganese steel liner. The size of the discharge port is adjusted by hydraulically or manually.

The name of the single-cylinder cone crusher is because it is supported by a hydraulic cylinder at the bottom to support its crushing force. Due to the high rigidity of the hydraulic medium, the load force of the crusher can be well supported. At the same time, the protection effect is better in overload protection, and the crushing force can be made larger. Improving the power factor, reducing the equipment and foundation. Facility investment. The hydraulic cone crusher is also better than the springs.

The single-cylinder crushing machines construction is relatively simple, and the feed size of the S-cavity cone crushers can be larger. The CC series single-cylinder cone crusher also has a relatively simple structure, easy to use and maintain. JXSC CC series single-cylinder crusher has been widely used in hydropower, nuclear power, highway, high-speed rail, stone, mining and non-metal mines, and has been fully recognized by users. Its performance is comparable to that of foreign mesto brands. Good equipment also needs good maintenance, so the machine needs to care. The working condition during the use process also determines the service life of the equipment. It is very important to always do the maintenance work on the equipment to ensure that the equipment works under normal working conditions. Due to the structure of the crushers, it should pay special attention to the problems of crowding the feed, the segregation of the feed, the drop of the feed, and the like. And minimizing the unnecessary impact to cause abnormal damage to the crushers.

The multi-cylinder cone crusher evolves from the original multi-spring cone crusher. The hydraulic instead of the spring has a better protection effect, and the crushing force can be made larger. Then it will more powerful and efficient. The hydraulic cone crushers are also better than the spring cone machine. However, the structure of the hydraulic cone crusher is relatively more complicated. The cost of one input is higher than that of the spring cone crushers.

Although single-cylinder and multi-cylinder are named according to the number of hydraulic cylinders, we cant simply understand that the construction of them is the same. There is a big difference between the two cones crusher. The multi-cylinder hydraulic cone has a broken load-bearing structure, and the main shaft is not as long as a single-cylinder hydraulic cone. The multi-cylinder hydraulic cone-breaking overload protection device locates outside the casing. There are multiple accumulators single or multiple safety valves If there is excessive iron or jam. Accumulator stamping, if the pressure continues to rise, the safety valve will relieve, the upper frame will rise. And the gap between the broken walls will increase, and the iron block or the stuck material will fall.

7 hammer crusher common problems and solutions

Hammer crusher is an equipment that uses impact form crushing materials. The crusher machine divides into a single rotor and a double rotor. The single rotor is divided into reversible and irreversible. The hammer crusher is widely used for fine crushing of medium hardness materials because of its high productivity and easy maintenance. The hammer mill crushers play an important role in the whole stone crusher plant. It will inevitably appear a variety of problems during hammer crusher working. The problems need to be resolved in time once find. This article will talk about 7 hammer crusher common problems and solutions.

Reason: improper bearing design selection. The processing accuracy of hammer crusher parts can not meet the requirements. Poor installation quality. Vibration factors. Poor lubrication, bearing wear and failure. V belt tension is too large. Improper maintenance methods. The environment temperature is too high.

Reason: Not crushing materials enter the hammer crusher machine. Lining fastener is loose and hammer strikes the lining. Hammer or other parts are broken. Solution: Stop and clean up the broken cavity. Check the tightness of the lining board and the clearance between the hammer and the screen. Replace the broken parts.

Reasons: replacement of hammerhead or cone headwear makes rotor static balance counter condition. Hammerhead broken. Rotor unbalance. Pin roll bending, broken. Triangular plate or disc cracks. Anchor bolt lose.

Solution: remove the hammerhead and choose hammerhead according to the weight which makes the total weight of hammer on each hammer shaft equal to the total weight of hammer on its relative hammer shaft. That is the static balance to meet the requirements

The so-called bearing locking is the bearing in the operation of a large number of heat. The heat in a short time can not be dissipated which leads to locking. This phenomenon in equipment as well as the production service site is very common. The specific causes of bearing heat have the following aspects.

Misfit of bearing outer ring and housing bore or bearing inner ring with shaft during assembly. Improper control of bearing heating temperature during assembly. Improper adjustment of bearing clearance during assembly. These three improper assemblies will cause the bearing heat, resulting in the bearing holding dead.

Oil Seal is used to seal the rotating shaft of mechanical equipment with oil seal components, and the cavity is basically static. So the oil seal is also known as the rotating shaft lip seal. For the oil seal with auxiliary lip, the auxiliary lip has the function of dust-proof which prevents the impurity invasion. And in order to prolong the life of the oil seal. The auxiliary lip often has bad lubrication, and the friction force is big which causes the oil seal to dry friction and the damage. So the installation of a double lip oil seal must be between the lips filled with grease.

During the assembly process, if the gauge is not carefully checked, the temperature will rise rapidly after a certain period of time. Bearing outer ring size has been determined by the end cover and the mouth of the bearing seat, the size of the diaphragm sleeve reduced. The size of the inner ring will be adjusted by the round nut, and finally compressed. the axial clearance of the bearing reduced, making it hot during operation.

Bearing Grease should not be too much. If fat amount is too large which will increase the friction Torque, bearing temperature rise. But if fat amount is too small that cant obtain reliable lubrication and dry friction. Generally speaking, the proper amount of grease is 1 / 3 ~ 1 / 2 of the total void volume in the bearing. Therefore, according to the use requirements, regular injection of the appropriate amount of grease.

Check whether the screw is loose, whether the lubrication is good, whether the parts damaged ( parts such as center feed pipe, conical cover, impeller, underflow liner, circumferential guards and jaws, etc.). Repair or replace in time if they worn out. At the same time, the weight, type, and size of the replacement part must be changed according to the original part parameters. It is best to check the equipment before use to ensure the normal operation of the equipment. Do those also can extend the life of the machine, reduce maintenance costs.

mobile crusher, mobile crushing plant- sbm mining and construction machinery

According to the practical using experience, we mainly developed three types wheel mobile crushing plantsmobile jaw crusher, mobile cone crusher and mobile impact crusher. With these crushing plants, both primary crushing and medium-fine crushing are able to finished in anywhere.

crushers - all crusher types for your reduction needs - metso outotec

All rock crushers can be classified as falling into two main groups. Compressive crushers that press the material until it breaks, and impact crushers using the principle of quick impacts to crush the material. Jaw crushers, gyratory crushers, and cone operate according to the compression principle. Impact crushers, in turn, utilize the impact principle.

As the name suggest, jaw crushers reduce rock and other materials between a fixed and a moving jaw. The moving jaw is mounted on a pitman that has a reciprocating motion, and the fixed jaw stays put. When the material runs between the two jaws, the jaws compress larger boulders into smaller pieces.

There are two basic types of jaw crushers: single toggle and double toggle. In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation causes, along with the toggle plate, a compressive action.

The chewing movement, which causes compression at both material intake and discharge, gives the single toggle jaw better capacity, compared to a double toggle jaw of similar size. Metsos jaw crushers are all single toggle.

Gyratory crushers have an oscillating shaft. The material is reduced in a crushing cavity, between an external fixed element (bowl liner) and an internal moving element (mantle) mounted on the oscillating shaft assembly.

The fragmentation of the material results from the continuous compression that takes place between the liners around the chamber. An additional crushing effect occurs between the compressed particles, resulting in less wear of the liners.

Cone crushers resemble gyratory crushers from technological standpoint, but unlike gyratory crushers, cone crushers are popular in secondary, tertiary, and quaternary crushing stages. Sometimes, however, the grain size of the processed material is small enough by nature and the traditional primary crushing stage is not needed. In these cases, also cone crushers can carry out the first stage of the crushing process.

Cone crushers have an oscillating shaft, and the material is crushed in a crushing cavity, between an external fixed element (bowl liner) and an internal moving element (mantle) mounted on the oscillating shaft assembly.

An eccentric shaft rotated by a gear and pinion produces the oscillating movement of the main shaft. The eccentricity causes the cone head to oscillate between open side setting and closed side setting discharge opening.

The fragmentation of the material results from the continuous compression that takes place between the liners around the chamber. An additional crushing effect occurs between the compressed particles, resulting in less wear of the liners. This is called interparticular crushing also.

Depending on cone crusher, setting can be adjusted in two ways. The first way is for setting adjustment to be done by rotating the bowl against the threads so that the vertical position of the outer wear part (concave) is changed. One advantage of this adjustment type is that liners wear more evenly.

To optimize operating costs and improve the product shape it is recommended that cone crushers are always be choke fed, meaning that the cavity should be as full of rock material as possible. This can be easily achieved by using a stockpile or a silo to regulate the inevitable fluctuation of feed material flow. Level monitoring devices detect the maximum and minimum levels of the material, starting and stopping the feed of material to the crusher, as needed.

Impact crushers are traditionally classified to two main types: horizontal shaft impact (HSI) crushers and vertical shaft impact (VSI) crushers. These different types of impact crushers share the crushing principle, impact, to reduce the material to smaller sizes, but features, capacities and optimal applications are far from each other.

Horizontal shaft impact (HSI) crushers are used in primary, secondary or tertiary crushing stage. HSI crushers reduce the feed material by highly intensive impacts originating in the quick rotational movement of hammers or bars fixed to the rotor. The particles produced are then further fragmentated inside the crusher as they collide against crusher chamber and each other, producing a finer, better-shaped product.

VSI crusher can be considered a stone pump that operates like a centrifugal pump. The material is fed through the center of the rotor, where it is accelerated to high speed before being discharged through openings in the rotor periphery. The material is crushed as it hits of the outer body at high speed and due to rocks colliding against each other.

Selecting optimal crushing equipment can be difficult. Luckily there are tools and software available that simplify weighting different options and help in making decisions. The backbone of all these analyzes are careful calculations that take into account the capabilities and constraints of different crushers and operational requirements.

Every crushing site and operation is different, and theoptimal results are normally obtained by combining theoretical conclusions with practical experience of different materials, operational conditions, maintenance needs, and economic aspects of various alternatives.

Below are some key issues listed according to crushing stages in brief. While defining the best technical solution for your requirements, its good to remember that many crushers are available not only as stationary but also asmobileorportableversions in case you prefer to move or transport your crusher at the production site or between sites regularly.

The main purpose of a primary crusher is to reduce the material to a size that allows its transportation on a conveyor belt. In most crushing installations a jaw crusher takes care of primary crushing. Plants with very high capacities that are common in mining and less popular in aggregates production, normally use a primary gyratory crusher. When the processed material is easy to crush and not very abrasive, an impact crusher may be the best choice for primary crushing.

One of the most important characteristics of a primary crusher is its capacity for accepting feed material without bridging. A large primary crusher is, naturally, more expensive than a smaller one. Therefore, the investment cost calculations for primary crushers are compared together against the total costs of primary stages, including quarry face clearing, blasting, and drilling costs. In many cases, dump trucks transport the rock to a stationary primary crusher. This may be an expensive solution. Amortization, fuel, tires, and maintenance costs can be included when the vehicles are in high demand. In modern aggregates operations, the use of mobile primary crushers that can move alongside the rock face is, in many cases, the most economical solution.

In terms of the size of the feed opening, the client gets a better return on investment when the primary crusher is a jaw crusher. That means less drilling and blasting because the crusher accepts larger boulders. The disadvantage of this type of crusher, when high capacity is required, is the relatively small discharge width, limiting the capacity as compared with the discharge circuit of a gyratory crusher. Jaw crushers are mainly used in plants producing up to approximately 1600 t/h.

The primary gyratory crusher offers high capacity thanks to its generously dimensioned circular discharge opening (which provides a much larger area than that of the jaw crusher) and the continuous operation principle (while the reciprocating motion of the jaw crusher produces a batch crushing action). The gyratory crusher has no rival in large plants with capacities starting from 1200 t/h and above. To have a feed opening corresponding to that of a jaw crusher, the primary gyratory crusher must be much taller and heavier. Also, primary gyratories require quite a massive foundation.

The primary impact crusher offers high capacity and is designed to accept large feed sizes. The primary impact crushers are used to process from 200 t/h up to 1900 t/h and feed sizes of up to 1830 mm (71") in the largest model. Primary impact crushers are generally used in nonabrasive applications and where the production of fines is not a problem. Of all primary crushers, the impactor is the crusher that gives the best cubical product.

If the intermediate crushing is done with the purpose of producing railway ballast, the quality of the product is important. In other cases, there normally are no quality requirements, except that the product be suitable for fine crushing.

Due to their design, cone crushers are generally a more expensive investment than impactors are. However, when correctly used, a cone crusher offers lower operating costs than a conventional impact crusher. Therefore, clients crushing hard or abrasive materials are advised to install cone crushers for the final crushing and cubicising stage.

Cone crushers can in most cases also give a good cubic shape to fine grades. They can be adapted to different applications. This is an important factor, as client-specific needs often change during a crushers lifetime.

The conventional type has horizontal shaft configuration, known as HSI. The other type consists of a centrifugal crusher with vertical shaft, generally known as VSI. Impactor operation is based on the principle of rapid transfer of impact energy to the rock material. Impactors produce cubic products, and they can offer high reduction ratios as long as the feed material is not too fine. This means that in certain cases it is possible to use a single impact crusher to carry out a task normally done in several crushing stages using compressing crushers (i.e., jaw, gyratory, and/or cone crushers). Impactors are mostly used for nonabrasive materials.

Conventional horizontal-shaft impact crushers are available in various sizes and models, from high-capacity primary crushers for large limestone quarries to specially designed machines for the crushing of materials such as slag.

There are two main categories of VSI crushers machines with impact wear parts around the body and machines that use a layer of accumulated material. The first type is in many respects similar to the conventional impactor with horizontal shaft and rotor. The second type became quite popular in the past decade and is known as the Barmac crusher. The difference between a conventional impactor and a VSI of the Barmac type is that the latter offers lower operating costs, but its reduction ratio is lower also. In a Barmac VSI, the material undergoes an intense rock-on-rock crushing process. In the other crushers, most of the reduction is done by the impact of stone against metal.

Customers operating old, rebuilt, or expanded plants often have problems with the shape of the product. In these cases, the addition of a Barmac VSI in the final crushing stage offers a solution to product shape problems.

The same applies to many mobile crushing units. As the number of crushing stages is normally small with this type of plant, it is almost impossible to obtain a good product shape unless the rock is relatively soft and thus more suited for the production of cubic product. A centrifugal crusher in the final stage can help to solve the problem.

Its main features are that it is movable and walking freely, thus, the transition is more convenient to ensure safe operation. The station's output ranges from 10 to 650 tons per hour, and one production line can simultaneously produce four sizes of stones, sand and powder.

The mobile crusher can carry jaw crushers, impact crushers, cone crushers, vibrating screens, conveyors, etc. The complete ore processing line has significant quality, performance and price advantages, and is widely used in highway, railway, national defense and construction.

The crawler-type: crawler-type drive has the advantages of lowering the chassis of the whole machine, strong driving stability. The whole machine can work at complex sites with strong adaptability, especially good for climbing work.

It can also quickly enter the work site for immediate operation. The whole machine adopts steel structure which is sturdy and durable. Modular assembly makes various devices work together without affecting each other.

It can be divided into jaw crusher type, cone crusher type, hammer crusher type, impact crusher type, etc., due to the different types of crushers it carries, its function and adaptability are also different.

The jaw crusher is suitable for coarse crushing, the cone crusher and impact crusher are suitable for fine crushing, the hammer crusher can be used for one-time shaping, and the impact sand maker is used for sand making. In short, the user needs to combine his own needs when configuring the machines.

The two-machine mode usually consists of a mobile jaw crusher + a mobile cone crusher or a mobile jaw crusher + a mobile impact crusher. The two stations form a production line covering the processes of coarse crushing, fine crushing, screening, feeding and transportation;

When configuring a mobile crushing station, there have differences between the large output and small output. Generally, the line is 40-50 t/h. The small output can be matched into one mobile station and the large one generally requires two or more. Next, lets take a look at the specific configuration of the mobile crusher.

As far as the situation on the market is concerned, there are two main types of suppliers of mobile crushers. One is to have their own factories and sell the mobile crushing station by themselves. These suppliers are called direct sales manufacturers. And the other one is that there have no factories of its own, which means that they need to purchase the mobile crushing plant from others, and then sell the machines by themselves. This kind of supplier is called a sales-oriented manufacturer.

For these two manufacturers, the mobile crusher and other equipment processed by the former are closer to the factory price. The latter, because of the price difference in the middle, will be more expensive than the direct-selling manufacturer.

From the above, it can be seen that the direct-selling manufacturers are more favorable in price. Also, for direct-sales manufacturers, the problems of after-sales and accessory support of mobile crushers can be better guaranteed.

Henan HXJQ Machinery is a direct selling manufacturer, specializing in the production of various types of mining equipment for 40 years, with advanced technology and rich experience.
