There are different types of stone crushers in mining industry such as jaw crusher, cone crusher, impact crusher, and sand making machine. This article will tell you how to maintain the 4 types of rock crushers and how to efficicently improve their performance.
Many stone crusher operators have a common coception that is "don't-fix-it-if-it-isn't-broke". They may want to save cost at the begining while the consequence is that they have to spend more money on repair and face interuption on production. That's why I always say that preventive and predictive is very important for all types of stone crusher.
Preventive means that by making regular checklist and inspections to keep crushers in good condition. Maintenance checklist is usually set up on a daily (8 hours), weekly (40 hours), monthly (200 hours), yearly (2,000 hours). Only doing that, can you prolong the machine's life span and maximize its value in crushing process.
Predictive refers to mornitoring the condition of crusher when it is running. By some maintenance tools such as lubricating oil temperature sensors, lubricating oil filter condition indicator, you can timely draw the machine data so that making a comparison between the real situation and normal state. Predictive can help you find problem early then timely removing thers issues before demage occuring.
Ractive means that even if your crushers have got problems, as long as you adopt correct solutions to respond, you still can get your machine back to normal. Next, I'll introduce important skills to maintain your equipment.
The cone crusher in the secondary or tertiary crushing proccess often fractures medium-hard or hard rocks like pebble, quartz, granite, etc. It is easy to get premature crusher failure, if operators cannot make a correct and timely inspection and maintenance.
Mantle in moveable cone and concave is fixed cone. Due to directly contacting with rock materials, the two wear parts need frequent maintenance and protection. So operators have to know the preparations and maintaining skills.
The working principle of impact crusher is that the spinning rotor under the driving of the motor can genetate strong impact force which make blow bars crush stone material into small pieces. Then the crushed material would be thrown by hammers towards, which makes another crushing process "stone to stone".
The sand making machine is also known as the vertical shaft impact crusher. Its working mode is that the material falls vertically from the upper part of the machine into the high-speed rotating impeller. The impeller is one of the important parts of the sand making machine, and it is also the most vulnerable part.
After the materials collide with each other, they will be pulverized and smashed between the impeller for multiple times and discharged from the lower part. The materials crushed by the device have an excellent particle size and are suitable for aggregate shaping, artificial sand making and highway construction.
In the face of such a dazzling market, how to choose the production equipment suitable for users' actual needs among the numerous equipment brands of many machinery manufacturers is a big problem for many large and small enterprises. Here we list top 4 world's construction equipment manufacturers for you to choose:

Many cement plants extract limestone by blasting, which often leads to oversized boulders containing a lot of clay and sand. The crusher therefore has to handle feed that contains larger blocks as well as some sticky materials. Our EV Hammer Impact Crusher is a proven, reliable and cost-effective impact crusher that help to overcome these crushing challenges.
In traditional hammer crushers with a top inlet, introducing large blocks in the feed can impede the action of the hammers and block the crusher. Our EV Hammer Impact Crusher, however, competently reduces quarry-size limestone boulders measuring up to 2.5 metres and weighing up to 5 tonnes to mill feed of 25 millimetres. This is a reduction ratio of 1:100 in a single operation. The EV Hammer Impact Crusher features a highly effective two-stage crushing process. Primary crushing takes place by impacting. Secondary crushing takes place by shearing and compression between the impact hammers and the breaker plate and between the hammers and the outlet grate. This ensures that even the smallest particles absorb energy and that no oversized particles leave the hammer impact crusher. The horizontal feed system can also tolerate coarse feed blocks because of its shock-absorbing inlet rollers.
The EV Hammer Impact Crushers throughput capacities range up to 2200 tonnes per hour (tph) with an outlet grate and 2500 tph without an outlet grate. Motor sizes are typically in the range of 500 - 2500 kW.
The hammer rows, which can vary depending on your crushing capacity needs, are arranged to provide complete coverage across the outlet grate. By arranging them in this way, the raw material can be crushed at multiple points increasing overall efficiency.
Adjustment of the spacing between the hammers, breaker plate and outlet grate can be optimised to compensate for hammer wear. Even when the hammers lose up to 30 percent of their original weight, the required product size curve is unaffected.
The adjustable outlet grate gives the EV Hammer Impact Crusher control of the maximum size of the product. The grate ensures a consistent flow to the conveyor and protects it against any sudden impact of material leaving the impact crusher at high speed. The grate also protects other nearby machinery from being damaged during operation.
The hold-up mechanism of the outlet grate generates a crushed product with a relatively high proportion of fines. In this way, more of the comminution work is moved from the less energy-efficient raw mill to the more energy-efficient hammer impact crusher.
The hammer rows are fitted in a staggered configuration to give complete coverage across the outlet grate. This provides several points for crushing of the raw materials, increasing the overall efficiency of the crusher.
The hammers are pivotally suspended from bolts and are symmetrically shaped. This reduces the full brunt from the contact between material and hammers, which protects the rotor and crusher housing. The hammers can easily be turned to reverse the leading and tracing edges for maximum service life.
Equipped with sturdy, replaceable grate bars supported by heavy cheeks, the adjustable outlet grate allows unique control of the mill feed size using hydraulic systems. This ensures a consistent flow to the conveyor. The outlet grate also serves as protection for the conveyor and other machinery such as reclaimers, sluices and mills, against operational upsets and mechanical damage.
A horizontal feed system incorporating one or two shock-absorbing inlet rollers helps to handle coarse feed blocks. The inlet rollers accurately control the feed to the hammer impact crusher and ensure a smooth and even flow of material. Whether one or two inlet rollers are used depends on the method of feeding the crusher.
Bolted-on, wear-resistant plates protect all exposed surfaces, including the adjustable breaker plates, from abrasive feed materials. The inlet rollers of the horizontal feed system consist of a cylinder and a concentric shaft driven by a separate motor. Rubber pads inserted between the shaft and the cylinder make the inlet rollers shock absorbent.
The hammer rotor assembly consists of a heavy-duty, forged shaft with a square cross section and is also fitted with rotor discs. The unique sandwich assembly of the discs is a robust construction, that helps prevent distortion and crack formation.
The top part of the EV Hammer Impact Crusher can be accessed by means of hydraulic cylinders. The supply package includes hydraulically-operated tools for fitting and dismantling of the heavy hammer bolts.
The hydraulic cylinders and tools are served by a mobile hydraulic power unit which can be stored in a separate room when not in use. A lifting yoke facilitates handling of the hammer rows when changing hammers. It also holds them in position when dismantling and fitting hammer bolts.

After that, the materials smaller than the size of the screen hole are discharged through the gap, while materials of larger size are left on the screen plate to continue to be crushed and ground by a hammer, and finally discharged through the screen plate.
The hammer mill crusher is mainly PC series. With the development of the industry, the hammer crusher is constantly being improved. The heavy hammer crusher is its upgraded version, and the PCZ is the main series.
In terms of applicability and principle, there is almost no difference between them, except the difference is in the configuration position of the production line and the performance of the hammer.
The heavy hammer crusher is used for coarse crushing of ore, that is, the primary crushing process. The hammer crusher in the projects, especially large-scale crushing production lines, is often used together with heavy hammer crushers for medium or fine crushing.
The hammer head of the heavy hammer crusher is heavier than that of hammer crusher, generally higher than 20kg, so the crushing force of the material is greater, and the material that can be crushed per unit time is significantly higher than that of the general hammer crusher.
2 The humidity of processing raw materials. If the humidity of the raw materials is too high, there may be a bonding phenomenon when the hammer crusher works, and the particle size of the finished product will not be uniform.

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. The production of mobile crushers includes tire type, crawler type, jaw crusher type, cone crusher type, impact crusher type, etc.

Sandrock Mining is a growing company with years of experience in produce and supply of wear parts such as the Bowl Liner, Mantle, Jaw Plate, Cheek Plate, Hammer, Frame, Linerand spare parts such as Bushing, Shafts, Gears, and so on.
Crusher Hammer is one of the main crusher wearparts in the hammer crusher,whichinstall on the hammer crusher rotor. When hammer crusher is running, the crusher hammer direct to hit the raw material. Hammer play an important role in crushing different types of materials,so there are kinds of material crusher hammer classification .
Forging hammer mainly use incrushing pebbles, coal gangue, limestone.Forging Crusher hammer with high-quality train wheel steel (65Mn material, good impact resistance, toughness, wear resistance, and not easy to break) the use of forging machinery repeatedly forging metal billet to produce deformation in order to obtain a certain mechanical properties , A certain shape and size, after a special quenching heat treatment methods to ensure that the work area of the hammer to be high hardness, high wear-resistant properties. Through forging can eliminate the metal in the smelting process, such as casting defects such as loose, optimize the microstructure, and because of the preservation of a complete metal flow line, forging mechanical properties are generally better than casting.
High manganese steel wear-resistant hammer, reliable quality, wear resistance three times more than traditional material crusher hammer.The crusher hammer is widely used in the new dry cement production line supporting large limestone crusher.High manganese steel crusher hammer have good toughness, good technology, low price.its main feature is the greater impact or contact stress under the action of the surface layer will quickly produce work hardening, the work hardening index higher than other materials 5 -7 times, the wear resistance can be greatly improved.
Highchrome hammer hardness is excellent, is a high-quality wear-resistant materials in the crusher support hammer and impact crusher has been widely used, but the high-chromium alloy toughness is poor, easy to break in the absence of support hammer shell.

2.Impact crushing equipment, such as impact crusher and vertical shaft impact crusher. Its characteristics are large material crushing ratio, simple structure, convenient maintenance of equipment, good product granularity and low loss of material compressive strength.
The common crushers used in sand aggregate production line, their advantages, disadvantages and application scope are as follows:Table of Contents 1. Jaw Crusher2. Gyratory Crusher3. Cone Crusher4. Counter-Impact Crusher5. Hammer Crusher
Counter-crusher, also known as counter-attack, 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 types, sizes and finished material requirements vary in a variety of configurations.
The impact 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. Widely used in building materials, ore crushing, railways, highways, energy, transportation, energy, cement, mining, chemical and other industries for medium and fine materials. The size of the discharge material can be adjusted, and the crushing specifications are diversified.
The impact crusher is named according to the working principle, that is, the material is crushed by the principle of counter crushing. It is a crusher equipment which is more fine than the jaw crusher. It is mainly used for fine crushing operations in the stone production line. The crusher cooperates to break. The impact crusher has the following five advantages in the process of crushing.
First, the impact crusher is more effective in dealing with materials with large moisture content, effectively preventing material blockage. When the moisture content of the treated material is too large, the feed chute and the counterplate of the impact crusher may be equipped with a heating device to prevent the material from sticking. The impact crusher does not need to be equipped with a bottom sieve plate to prevent clogging.
Second, the impact crusher is suitable for a wider range of materials. The hammer of the impact crusher is fixed to the rotor by a mechanical clamping structure, and has a large moment of inertia when it rotates with the rotor. Compared with the hammer crusher (the hammer is in a suspended state), the rotor of the impact crusher has greater momentum, adapts to crushing harder materials, and has lower energy consumption.
Third, it can be convenient and flexible to adjust the particle size of the discharge, and the adjustment range is wide. The impact crusher can adjust the discharge granularity in various ways, such as adjusting the rotor speed, adjusting the backlash plate and the gap of the grinding cavity. The gap adjustment can be adjusted mechanically or hydraulically, and the hydraulic adjustment system facilitates the adjustment of the gap through the local operation button or the travel control system.
Fourth, the wearing parts of the wearing parts are small, the metal utilization rate is high, and the wear of the counter-attack type stone-breaking machine hammer is only present on the one side facing the material. When the rotor speed is normal, the feed will fall to the surface of the hammer (the striking surface), and the back and sides of the hammer will not be worn. Even the wear on the side of the material is scarce. And the bottom grinding rod is also easy to replace. The metal utilization rate of the impact crusher plate hammer can be as high as 45% 48%.
5. The spare parts of the impact crusher are easy to replace and the maintenance cost is reduced accordingly. Only 6 hammers are installed on the rotor of the impact crusher. The special tools can be used to easily replace the hammers. The time of a shift.
(2) Low operating costs and low investment costs. The total weight of the impact crusher is lighter than that of the hammer crusher, the shape is small, and the dynamic and static load values are low, which can effectively reduce the cost of civil works. At the same time, the required motor power is low, which can effectively reduce the power consumption of the device and reduce the operating cost of the device.
When the impact crusher is in operation, it can handle materials with a large moisture content, and can prevent the material from being blocked during the dust removal process. When the material with relatively large water content passes through the impact crusher, the feeding tank and the counterattack plate of the counterattack plate can be equipped with a heating device, the main function is to prevent the adhesion of the material and the counterattack plate, and the counterattack is not required to be equipped with the bottom sieve plate. Can effectively block the blockage of materials.
The impact crusher has a variety of applications, which can crush hard materials or break soft materials. The hammer of the counter crusher is firmly fixed to the rotor by a mechanical clamping structure, and has a large moment of inertia when the rotor rotates. The counter-attack crusher rotor has more power to accommodate the crushing of harder materials while consuming less energy.
The output size of the impact crusher is flexible and adjustable, and the range is relatively wide. The counter crusher can adjust the discharge particle size by adjusting the rotor speed and adjusting the gap between the counter plate and the crushing chamber. The gap adjustment can be mechanical or hydraulic, and the hydraulic adjustment system can easily adjust the gap through the on-site operation button or distance control system.
The impact crusher of the impact crusher has less wear and tear, and the utilization rate of the metal wearing parts is high. The wear of the counter-offer breaker hammer appears only on one side of the panel material. When the rotor speed is normal, the feed will fall on the surface of the hammer (the striking surface), and the back and sides of the steel hammer will not wear. Even on the side of the material, there is little wear. The bottom grinding rod is easy to replace. The metal utilization rate of the counter-attack crusher plate hammer can reach 45%48%. The hammerhead of the hammer crusher is suspended and the wear occurs on the top, front, back and sides. Compared with the hammer, the hammer wear is more serious, and the metal utilization rate is only about 25%. The rotor itself may wear out.
The replacement of the spare parts of the impact crusher is simple and the maintenance cost is reduced accordingly. Only a few hammers are installed on the rotor of the impact crusher (the equipment of different manufacturers may have different number of hammers). It is convenient to replace the hammer with a special tool, and only one shift is required to replace the set of hammers. The replacement of the bottom grinding chamber grinding rod can only take a few + minutes, which greatly reduces the time and cost of inspection and maintenance.
With the prosperity and development of the crushing industry, rock crusher is becoming more and more important.

The working principle of jaw rock crushers for sale is: when the stone crushing equipmentworks, motor drives belt and pulley to move, and the eccentric shaft drives the mobile jaw plate. When the mobile jaw plate rises, the angle between elbow plate and mobile jaw plate becomes larger. So the mobile jaw plate will be close to the fixed jaw plate. At the same time, materials can be crushed. When the mobile jaw plate down, the angle between elbow plate and the movable jaw becomes small.In addition,under the effect of rod and spring, the mobile jaw plate will be far from the fixed jaw plate. Meanwhile, the finished products will be discharged.
Crushing chamber of the gold rock crusher is composedof a fixed jaw plate and a mobile jaw plate. The latterplate is periodically reciprocated against the fixed jaw plate, sometimes separated, and sometimes closed. When they are separated, the material enters the crushing chamber and the finished product is discharged from the discharge port. When they are closed, the material between the two jaw plates is crushed by crushing, bending and splitting.
In short, this is how acrusher works. If you still have questions about the working principle ofthecrusher, you can contact us online or send us an e-mail. Aimix will provide you more detailed informations (such as: rock crusher youtube).
Impact crusher has wide applications. This kind of rock crushing equipment for sale has become the crucial equipment to crush stone materials in highway, high-speed railway, water conservancy project and other fields. The crusher for sale can processall kinds of coarse, medium and fine materials, such as: limestone, feldspar, calcite, granite, talc, barite, fluorite, rare earth, coke, coal gangue, gypsum, etc. Besides, this type of small rock crusher can be used inmetal and non-metallic mineral, metallurgy, cement, chemical, refractory, ceramic and other industrial sectors.
The mini rock crusher for saleis a crushing machine that uses impact energy to crushmaterials.Then, how does an small portable rock crusher for salework?When impact crusher is working, the rotordrivenby the motor has high-speed rotation.When the materials gointo the plate hammer area, they could be crushed byplate hammer on the rotor. Then materials are thrown to the counterattack device to be crushed again,and they are re-brokenbyhammer.The process is repeated, and the materialscan be repeatedlycrushed bythree counterattack cavitiesuntil the materialsare crushedto the required size. And then they are discharged from the discharge port.
In order to design and develop the perfect rock crusher plant, Aimxs experts have made great efforts. And this kind of crushercombineshigh crushing chamber and high crushing frequency. Moreover, Aimxs will introduce the working principle of rock crushing plant for sale.
When the mobile rock crusher for sale works, the V-belt, pulley, drive shaft, small bevel gear, and large bevel gear driven by the motor drive the eccentric sleeve to rotate. The axis of the rock crusher cone driven by the eccentric shaft sleeve swing rotationally, so that the surface of the crushing wall sometimes approaches and sometimes leaves the surface of the mortar wall. Therefore, materials in the the ring crushing chamber composed of fixed cone and mobile cone can be crushed by impacting, squeezing and bending constantly. After repeated squeezing, impacting and bending, materials can be crushed to the required particle size and discharged from the lower part.
In the case of unbreakable materials go into the crushing chamber or the machine is overloaded due to some reasons, the spring insurance system will work. The discharge port will be enlarged, and the unbreakable materials are discharged from the crushing chamber. If the impurities can not be dischargedwe can use cavity cleaning system. So that the discharge port will continue to increase. And the impurities can be discharged from the crushing chamber. Under the effect of the spring, the discharge port will automatically reset, and the gold crusher machine will back to normal work.
