Impact crusher is an important secondary crusher, while the primary crusher is the jaw crusher. This impact crusher is usually used for fine crushing and we will introduce you some basic information on impact crusher as follows, hopefully you can make a reference.

Impact crusher is a popular kind of crushing equipments featuring its high efficiency, small volume, simple structure, high crushing rate, low energy consumption, big outputs, even distribution of fineness and the selective crushing function, However, the  weakness of this crusher is the easy abrasion to blow bars and impact packs, especially for the hard stones, which needs regular replacement. Thanks to some wear-resistant materials, the impact crusher gets access to metallic mining plants. The impact crusher is widely applied in the metallurgy, the mining industry, the concrete preparation, the chemical industry, the ceramic and other industrial sectors like highway construction, water reservoir project, construction crushing and sand making industry.

The impact crusher uses impact energy to crush materials. When materials get into the area where the board hammer is, the crushed ones are thrown to the impact device above the rotor continuously under the impact function of board hammer at a high speed. Then they are rebounded from the impact liner back to repeat the above process. The unqualified materials will get into the impact cavity for being crushed repeatedly. The process is going on until the materials are crushed to the required fineness and then discharged from down of the machine.
