4 types of stone crushers' maintenance and efficient improvement | fote machinery

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.

Processing Materials: river pebbles, granite, marble, limestone, fluorite ore, gold ore, barite, calcite, dolomite, bluestone, glass, basalt, iron ore, etc.

The cone crusher is a kind of stone crusher machine applied for metallurgy, building, road construction, chemical engineering, etc. It is suitable for medium and fine crushing with the features of high crushing ratio, high efficiency, low energy consumption and uniform particle size.

There are different models in HXJQ divided by different crushing principles and different particle sizes: single cylinder hydraulic cone crusher, multi-cylinder hydraulic cone crusher, hydraulic cone crusher, Symons cone crusher (compound cone crusher), and spring cone crusher. At present, the most advanced one is the single cylinder hydraulic cone crusher, and the most popular one is the Symons cone crusher.

The structure of single-cylinder hydraulic cone crusher is simple. Its characteristics are the steep cone, high swing frequency, and small eccentric distance. The unique design structure of bottom single cylinder can complete the three functions which can adjust the discharge opening directly, prevent ferric materials, and clear chambers.

The Symons cone crusher has the hydraulic chamber-cleaning system which can reduce its downtime. This machine adopts the lubrication grease system which avoids the defects of water-supplying and discharging block as well as mixing the water and oil easily. The spring insurance system is an overload protection device, which can make the foreign matter and iron ore go through the crushing chamber without damage.

When the single-cylinder hydraulic cone crusher is working, the motor drives the small gear of the crusher, the pinion drives the large gear, and the large gear assembly drives the eccentric sleeve assembly and the spindle assembly, which are centered on the theoretical vertical line, and rotate in the copper bushing.

The spindle assembly in the eccentric copper sleeve with the center line of the spindle can realize the rotating material being crushed by the swinging inner cone, and the crushed material is discharged from the discharge port.

When the compound cone crusher is working, the motor drives the eccentric sleeve to rotate by the V-belt, transmission shaft and bevel gears. The moving cone rotates under the action of the eccentric sleeve. The material is continuously crushed and impacted in the crushing chamber, then the needed size of the material after crushing will falls under the gravity and be discharged from the bottom. Symons cone crusher controls the particle size of material according to reducing the size of the discharge opening, so it is not suitable for ultra-fine sand or sand making.

The technology of single-cylinder hydraulic cone crusher is more advanced and higher efficient to operate. Under the condition of the constant crushing chamber, the maximum feeding size and productivity can keep constant, it has higher output, longer liner life, and lower operating costs. Its mainframe weight is 5700 to 36,300 kg, the weight of Symons cone crusher is 9980 to 43,270 kg, and its volume and weight are smaller than Symons cone crusher. Therefore, it is more convenient and quick to install and transport, as well as lift and change parts.

Jaw crusher, cone crusher and impact crusher are the mainstream crushers used in mining industries. Jaw crusher and cone crusher are the classical laminated crushers, and also the most popular crushers, while impact crusher adopts impact crushing principle. In general, jaw crusher is used as the primary crusher, and cone crusher and impact crusher as the secondary. And they always combine with each other in the whole crushing line during the crushing process.

Jaw crusher and cone crusher adopt the laminating crushing principle, known as extrusion crushing principle. Although the crushing actuators are different, the nature of crushing does not make much difference.

During the crushing process, the cone crusher adopts the extrusion between the mortar wall and the crushing wall, and the jaw crusher adopts the extrusion between the mobile jaw and the fixed jaw.

Impact crusher adopts the impact crushing principle, and materials are impacted and crushed between hammer and impact plate. Due to the frequent impact, the wearing parts are easy to damage, so impact crusher has a high requirement on the wear-resistance materials.

The jaw crusher, cone crusher and impact crusher are widely used in a variety of materials, but they have different applicability. The jaw crusher can almost meet the requirements of all materials.

Cone crusher also has the wide applications, ans it can crush high-hardness materials in high efficiency. However, impact crusher is generally used for crushing soft materials such as limestone because its crushing principle and wear-resistant parts, and impact has a good performance in shaping.

When choosing crusher machines, a comparison should be conducted according to different situations. Generally, jaw crusher is used for primary crushing, and for second crushing or fine crushing, a large ore-dressing plant always chooses the cone crusher, and a medium or small plant chooses the impact crusher.

Generally, jaw crusher is suitable for all kinds of crushing lines, and it is relatively cheaper than cone crusher because of the large market. Though impact crusher has a cheap price, it has several wear-resistant parts such as hammer and impact plate, which should be replaced after several times uses, so impact crusher has a high using cost.

Although cone crusher is relatively expensive, the wear-resistant parts have long service life to avoid the worries of changing parts frequently. Therefore, cone crusher has higher performance-price ratio than impact crusher in the long run.

HXJQ as a professional cone crusher manufacturer has produced crushers for more than 40 years, and we have the crushers with the lowest cone crusher prices and highest quality. If you have any problems in the selection of equipment, please timely consult HXJQ, there are experts who will guide for you in the whole process and choose the most suitable, cheapest, and best-performance equipment for you.

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

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.

If you are interested in more detailed analyzes tailored just for your crushing operations, please contact Metso experts. We have practical experience of thousands of different crushing applications around the world, and we are happy to help in finding the equipment that best fits your needs.

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.

Every crushing site and operation is different, so the choice of the crusher depends on the material to be processed and the ideal size of the final product. Selection may seem difficult, but luckily there are tools and software available that simplify weighting different options and help in making decisions. The backbone of all these analyses is careful calculation that takes into account the capabilities and constraints of different crushers and operational requirements. This includes combining theoretical conclusions with practical experience of different materials, operational conditions, maintenance needs, and economic aspects of various alternatives. Simply put - determining which technology is the most suitable option for production with the least possible stages.

All rock crushers can be classified as falling into two main groups. Compressive crushers that press the material until it breaks, and impact crushers that use the principle of quick impacts to crush the material. Jaw crushers, gyratory crushers and cone crushers operate according to the compression principle. Impact crushers, in turn, utilize the impact principle. Another way to classify the equipment is according to the stage where they are allocated in processing. For instance jaw or gyratory crushers in primary crushing and cone crushers in secondary crushing.

The very first crushers invented were jaw crushers, which are built to reduce the size of large materials and operate with high volume in primary crushing. Their main purpose is to reduce the material to a small enough size that it can be transported to the next crushing stage by conveyors. Jaw crushers can also be successfully applied in the recycling operations. The mechanics are quite simple, which makes the installation and maintenance easy.

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

Jaw crushers can be divided into two basic types, single and double toggle. In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation, along with the toggle plate, causes a compressive action. A double toggle crusher has two shafts and two toggle plates. The first shaft is a pivoting shaft on the top of the crusher, while the other is an eccentric shaft that drives both toggle plates. 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.

Another type of crushers often used in the primary crushing stage is gyratory crushers that have an oscillating shaft. The material is reduced in a crushing cavity, between an external fixed element, a 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. The gyratory crushers are equipped with a hydraulic setting adjustment system, which makes it possible to regulate the gradation of the crushed material.

Cone crushers resemble gyratory crushers from the 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.

The cone crushers are equipped with a hydraulic setting adjustment system, which adjusts closed side setting and thus affects product gradation. Depending on the cone crusher, the 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. Another principle is that of setting the adjustment by lifting or lowering the main shaft. The advantage of this is that the adjustment can be done continuously under load.

To optimize operating costs and improve the product shape, it is recommended that cone crushers are always 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 the 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 use the principle of quick impacts to crush the material and they can be used in any stage of the crushing process. However, the features and capabilities of different impact crusher types vary considerably.

Impact crushers are traditionally classified into 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 crushers are used in primary, secondary or tertiary crushing stage. They 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.

Vertical shaft impact crushers, on the other hand, are used in the last stage of the crushing process, especially when its required that the end product has a precise cubical shape. 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.

During the last decades, the evolution of crushers has led to the reduction of costs, increase in production and greater energy efficiency. In practice, this means for instance easier installation and greater capacity of gyratory crushers as well as growth in the production capacity and improved lubrication systems of jaw crushers. Cone crushers, instead, have become increasingly automatic and are not restricted to the processing of hard rocks.

Computer simulations improve the choice of models, using real data from the ore or rock, and automation corrects and adjusts the crushing operation in real time, on a daily basis. Even though the hardware has evolved greatly, it is the software that dictates the development of crushing today.

5 types of stone crushers | application and maintenance

5 types of stone crushers | application and maintenance

Stone crusher is mainly used for crushing operation in quarry crushing plant and mining plant. There are 5 types of stone crushers: jaw crusher, impact crusher, hammer crusher, cone crusher, and VIS crusher. What is the application of the 5 types of stone crushers and how to maintenance? This article is about a thorough introduction.

Jaw crusher is a heavy-duty which crushing the hard rock. Therefore, the jaw crusher parts need to be very hard and durable. In particular, the two components of the jaw crusher work, the fixed jaw, and the movable jaw. The crushers machine are widely used in industries of mining, building materials, roads, railways, water conservancy, and chemical. The types of jaw stone crusher: single toggle jaw crusher and double toggle jaw crusher.

During the maintenance of the jaw crushers, wear part is a common occurrence. This is also the main wear in the stone crushing line. Therefore, we recommend that customers purchase high-quality jaw crushers, which are more durable and have better running performance. During use, it can avoid many unnecessary wear problems and reduce the trouble of frequently changing parts. 8 notes of jaw crusher routine maintenance.

1. Check the heat of the bearing. The temperature of rolling bearings doesnt exceed 70 C. If exceeds the specified temperature, it must stop and immediately check and troubleshoot. 2. Check whether the lubrication system is normal. Whether there is a crash of a gear oil pump. Observe the value of the oil pressure gauge and check whether the lubrication system in the fuel tank leaks oil. If find the above various conditions are abnormal, dealt with they in a timely manner. The place of movable jaw suspension bearing and the elbow, it should lubricate regularly which automatic or manual oil pump lubrication. 3. Check whether the oil contains metal powder and other contaminants. If there is dirt, stop the bearing and other parts to check. 4. Check whether there are loose joints between the bolts and flywheel keys of each part. 5. Check the wear of the gear plate and transmission components, and whether the lever spring is normal. 6. Always keep the equipment clean, so that there is no dust, no oil, no oil leakage, no water leakage, no leakage, no leakage. Especially pay attention to prevent dust from entering the lubrication system and lubrication parts. 7. Clean the filter cooler regularly, and wait until it is completely dried before washing. 8. Regularly change the lubricating oil in the fuel tank. Usually once every six months.

The impact crusher crushing the soft and very hard materials, even if there is moisture in the material. The types of stone crushers are widely used in building materials, ore crushing, railways, highways, energy, transportation, energy, cement, mining, chemical and other industries for medium and fine materials.

1. The jaw crushers run smoothly. When the vibration quantity of the machine suddenly increases, it should stop immediately to find out the cause. 2. Under normal conditions, the temperature rise of the bearing should not exceed 35, and the maximum temperature should not exceed 70 . If it exceeds 70, stop immediately and find out the cause. 3. When the plate hammer wear reaches the limit mark, it should be turned around or replaced in time. 4. After assembling or replacing the hammer, it must maintain the rotor balance, and the static balance should not exceed 0.25kg.m. 5. When the rack lining wear, replace it in time which can avoid wearing the casing. 6. Check the tightening status of all bolts before starting each time.

1. Always pay attention to and timely lubrication of the friction surface. 2. The lubricating oil used in the impact crusher should be determined according to the location of the crusher machine, temperature, and other conditions.

Cone crusher is an advanced hydraulic crusher with high power, large crushing ratio, and high productivity. Generally, it uses as a secondary crusher to break medium-hard materials, and use as fine crushers in artificial sand making process plants and quarry plant. Cone Crusher is a hydraulic crushing machine suitable for use in raw materials in the metallurgical, construction, road construction, chemical, and silicate industries. Types of cone stone crushers: GP cone crusher namely single-cylinder hydraulic cone crusher, HP cone crusher namely multi-cylinder hydraulic cone crusher, Compound cone crusher.

1. There must be a de-ironing device to prevent the crushing chamber from passing through the iron. If the iron is frequently over-exposed, it may cause a shaft breakage accident. 2. To be fully loaded, otherwise, the product size will be too thick. 3. The crushing ratio in the production line should be reasonable, so as to maximize the efficiency of the crusher. 4. The spring pressure should not be too tight. If the pressure is too high, the shaft breakage will occur. If the pressure is too small, the spring will jump frequently which affecting the normal operation of the crusher. The product size will become thicker. 5. The temperature of the lubricating oil should not be too high or too low. Otherwise, it will affect the operation of the machine. 6. A lubricating oil should be replaced frequently. Not too dirty. If it is too dirty, it will accelerate the wear of gears, bowl-shaped tiles, bushings, etc., and even make the bushings die. 7. The drive belt installation should not be too tight. Otherwise, it will cause the driveshaft to rotate inflexible or broken. It should not be too loose, otherwise, it will cause the crusher to suffocate. 8. The feeding material should not be too wet and too sticky, the fine particles should not be too much, and it should not be too big. Otherwise, it will cause boring.

Hammer crusher is a high-speed rotary crushing machine. The crusher is suitable for crushing medium hardness materials in industrial sectors such as cement, chemical, electric power, and metallurgy. The medium hardness materials such as limestone, slag, coke, coal and other materials in the medium and fine crushing operations. The hammer mill rock crusher can be used not only for crushing plant, sand making plant, it also can replace cone crushers in mining plant. The types of stone hammers crushers: single-stage hammer crusher, high-efficiency hammer crusher, sand making machine, vertical shaft hammer rock crusher, reversible hammer crusher, double rotor hammer crusher, ring hammer crusher.

1. It should contact the upper and lower procedures related to the machine before starting to stop. And perform the correct operation in the order of opening and stopping. 2. To start the empty machine and should empty the material in the crushing chamber and then stop. 3. Always check all the anchor bolts and lining bolts of the equipment for looseness. If loose, tighten them in time. 4. Check the use of easy-to-wear and easy-to-wear parts such as hammerheads and linings. If we find the problems, they should be disposed of in time. 5. Look at the lubrication and keep the lubrication system in good condition. 6. Keep the feed even and take care not to feed metal debris. 7. Pay attention to check whether the discharge granularity meets the quality requirements. If it does not meet, replace the purlin or adjust the height of the purlin bracket.

VSI crusher is a kind of sand making machine which uses in sand plant and quarry plant. The VSI sand making machine is a hydraulically impact sand making machine that is 50% more energy-efficient than conventional machines. It can make all kinds of rocks, sandstones and river pebbles with construction sand of various grain sizes. The uniformity of sand and high compressive strength.

Firstly, the inspection of sand making equipment before starting. Check whether the machine cavity inspection door is closed. If no close, close it to prevent the material from flying out and posing a danger to the staff. And the lubricating oil of the equipment should also be inspected.

Thirdly, the starting sequence of the VSI series crushers must be correct. It is generally installed in the following order: vibrating feeder jaw crusher sand making machine vibrating screen sand washing machine. In the event of a shutdown, you need to operate in reverse order.

Finally, it is necessary to ensure the normal feed rate and volume of the equipment during the production process. We must strictly follow the feed size required by the equipment. Forbidding to enter metal materials and large stones to prevent damage to the parts of the equipment. If we find severe vibration or loud noise during the production process, stop and inspect in time for timely treatment.
