No matter what you are doing, building a house or constructing a road, in order to build the base of the structure, you may need the rock's help, certainly, what you need is not the raw rock, but the processed rock with much smaller size. Why is the rock needed? Because it is strong enough to hold up the total weight of the structure. And now the problem we are facing is that how to get rock materials with much smaller size. Generally speaking, the raw rocks directly mined from the ground are always with large size, for instance, some of them may be as large as your bedroom or even larger, and in this case, in order to get suitable raw materials, we need the help of the jaw crusher.

Impact crusher crushes the materials with shock energy. During the operation, rotor spins quickly under the drive of motor, materials are crushed by the apron hammer when materials are conveyed to the area of apron hammer. And then, the materials are threw to the counter device and be crushed again. After that, the materials are rebounded to the area of apron hammer from the impact plate to be crushed again. This progress circle will continue over and over again.

VSI crusher is short for vertical shaft impactor crusher. Both VSI and cone crushers are the popular crushing machines used to minimize the size of rocks. The size of rocks or other hard materials can be reduced and the shape of these materials can be shaped more perfectly. It seems that VSI and cone crusher are performing the same functions, however, there are amounts of differences between them. In the next, we will talk about the differences from three aspects: the working principle, the property of raw materials and final products. And we hope that the information can inform you of the desired knowledge.

As is well-known, stone crusher bearing undertakes the entire load of the stone crusher, so favorable lubrication has a great impact on the maintenance of the stone crusher's bearing. It affects the life of the machine and the operation rate directly, thus the oil that is injected into the stone crusher must be clean and sealing property must be very good.

With the improvement of extractive and the increased block size of extractive material, single rotor impact crusher limites the increase of feeding particle size due to its own structure, thus double rotor had been created out. In order to increase the role of the second rotor, double rotor impact crusher with height difference came after. Going back to the energy-linear formula, we can see that the first rotor crushes the materials in a lower speed while the second one go with a higher speed, as a result, reduction ratio has improved.

Cutting, punching chisel, crushing, grinding are the general four ways. Rock crusher, rock tools into the rock, and within the tool moving in front of the rock mass, is a dense core. Around the dense nuclear broken body produces a large crack. Mechanical crushing is not widely used in hard rock. It is the main reason of the tool wear. Rock crushing is mainly depends on the degree of wear and tear of rock within the content of hard minerals and particle size.

The most important thing is setting safety protection facilities and tags in dangerous position. Then check all the lubrication and hydraulic equipment if they are filled with standard lubrication grease and operation medium. Then inspect the inside body of stone crusher to see if any metal or other materials are left. If so, clean the inside body as soon as possible. And then, to make sure if the repair person has left the operating place. After that, check all the fastening parts to see if they are fastened or not and fasten the loose parts immediately. Then, you should make sure that all the doors and inspection plates are closed.

Prior to purchasing stone crusher, the type you need to choose should be predetermined. Amounts of types of crushers are available in the market. The production line of rocks can be separated into different process. You need to consider which process you need to complete before making the order. As a type of heavy machines, crushers can be extremely expensive and that is why some clients turn to buy the used type. Well, it is not recommended to do that since the quality of the used machine may could not guarantee the safety any more.

To put it simply, the rock crusher can be separated into primary and secondary crusher. Both the latter and former type can be used to break down stones. The crushed stones are the essential elements for several industries. For example, the small rocks are used for the construction of landscaping. It is obvious that the materials used for different applications feature different characteristics. Generally, primary crushers are used to prepare smaller particles for secondary stone crusher. And the secondary crusher can reproduce the smaller particles to make them more qualified.

The impact crusher, one of the popular rock crusher equipment, is a piece of equipment application with shock principle, the materials in the crushing cavity suffer a high speed crushing with the high-speed rotating hammer, and the crushed materials rush over to the impact plate and coming back again.

Generally speaking, the rock crusher can be divided into two kinds. One is medical rock crusher and the other is mining rock crusher. The medical crusher is mainly applied to the crushing of the calculus, usually in order to avoid the risks that the operations bring, it uses resonation to crush the calculus.

Based on the crushing characteristics, the gradation of the materials and the volume of the final product, it is essential to choose the right stone crusher and to make sure that the machine is made with experienced craftsmanship. Run at lower speeds, rock crushers are capable of processing materials into smaller particles with less consumption of energy. In most cases, the semi-products are irregular and require further crushing, washing and selecting.

The development of human civilizations never stop and one of the main factors to determine the level of civilization is the qualification of the buildings. It is easy to tell the difference between a modern skyscraper and the ancient house.

Stone crusher can also been used into the fuel or semi-broken materials' compressing, transporting and perhaps storage, which make the capacity and efficiency of the stone crusher be the key to the productions. As we know, the process of the crushing takes large amount of times and money. Therefore, there are quite a lot of factors that you need to pay attention when you operate such machine.

With the national economic development brought by the Reform and Opening up Policy, market demand is driving the development of impact crusher. Among the basically used five types of crushers, impact crusher belongs to the machine which crushes brittle material mainly with impact power.

Ancient crushing machinery was created one after another after the gradual promotion and perfection of the steam engine and other motive power machines. In 1858, the American people Black invented jaw crusher which is capable of breaking rocks; In 1878, the United States developed spiral crusher with continuous crushing actions, and its production efficiency is higher than the jaw crusher with interval crushing actions.

As the crushers are used to impact and crush hard materials, it'll be easy for crushers to be damaged without proper operation. And the impact crusher will not work perfectly if the crushers are not kept in good repair. So the follows will let you know how to prevent the impact crushing machine from damage and improve the maintenance quality of impact crusher.

Mobile crusher as well as cone crusher and impact crusher is a novel rock crushing equipment which largely extends the conception area of coarse crushing operation. It is designed to take removing obstacles brought to client from crushing places and environment as the main resolution, in the shoe of clients. And it also aims to provide client a basic equipment for operating project with high efficiency but with low cost. Then the advantages that the mobile crusher possesses will be stated for you. So you will know why the mobile crusher is a good choice.

Crusher is a quite common machine used in mineral industry mainly to crush all kinds of stone materials and the particle size of products is different according to the different crushing theories. The layout whose particle size is longer than 3mm exceeds 50% in the total layout. Of course there are many types of crushers, such as cone crusher and impact crusher, however, we are not gonging to give more detailed statements of those but spend more time on the rush issue of crushers--blocking up.

It is no wonder than everyone will complain of the construction projects near their house. The loud noise and unpleasant dust can not be beard by any normal people. To regulate the construction industry and minimize the impact to residents, the government has issued series of rules to control the construction projects near residential areas.
