Impact crusher is a new developed and high efficiency crushing equipment on the basis of hammer crusher, which is widely used in the non-metallic mines, building materials, chemical industry, coal, metallurgical and other industrial sectors that used for limestone, asbestos, coal, quartz sand, calcium carbide, dolomite, sulfide ore or other materials in coarse, medium and fine crushing. Why impact crusher can be so widely used? Compared with other types of crusher, it has the following advantages:
(1) When crushing materials, the impact crusher can make full use of the energy of whole rotor, so its crushing ratio is big. Therefore, it can reduce the crusher stages, simplify crushing production process, reduce construction investment and maintenance cost.
(2) Due to the crushing materials of impact crusher use the high speed impact principle, after repeated shocks and blows, which will be fractured along with the crystal boundary and the texture of material. As a result, higher crushing efficiency, less energy consumption.
(3) The adaptability of impact crusher is very strong that can crush kinds of materials such as hard, soft, crisp and toughness and fibrous materials, as well as the shape of products mostly are cube shape and more even. Therefore, it is suitable for many industrial sectors, especially the cement and building materials industry.
(4) The impact crusher can do the selective crushing, which can make the symbionts mineral in the ore and rock separated along with the crystal boundary, not destroy or rarely destroyed ore grain crystal.
(5) The impact crusher is of simple construction, smart quality, easy manufacturing, low cost, and convenient operation and maintenance.
The disadvantages of impact crusher are: flat hammer and impact plate are easy to be worn, especially when crushing the hard material, the wear is more faster, and the flat hammer and impact plate will be replaced frequently; poor adaptability of water and mud; large noise and big dusty at work.
