Unique Features of Impact Crusher

Impact crusher is a kind of machine which is similar to hammer breaker which is mainly to impact brittle things. It is used for items that has granularity no more than 500mm, and comprehensive strength of no more than 350Mpa, such as concrete, granite and limestone. It is widely used in variety stone crushing, construction of railway, highway, and energy, chemical and building industries. The size of layout granularity can be adjusted. Impact crusher has various crush standard, large reduction ratio and high crushing efficiency. What is more, it is convenient to repair if there is something wrong with it. It is the idealist devices for infrastructure and building construction.

Impact has the ability of dealing with high moisture content items effectively so that to prevent congestion in it. When it deals with high moisture content items, there can be installed a heat device between chute and counter-attack board to prevent stick of material.

Impact crusher is fit for both soft material and hard material. Hammer board of impact crusher is fixed at the rotor stably so that produces powerful momentum when rotor rotates. Compared with hammer crusher, rotor of impact crusher has a more powerful momentum which adjusts for harder items and low the energy-consumption at the same time.

Impact crusher can adjust the size of layout material freely according to several of ways. For example, adjust speed of rotor; adjust counter-attack board and grinding of impact crusher. And grinding adjust can be finished mechanically and hydraulically.

Breakdown of quick-wear part of impact crusher is not as frequent as hammer crusher. It has a higher metal utilization than hammer crusher as well. As for impact crusher, the breakdown can be happened only on the side of facing with material. When rotor is in normal speed, the feedstock will drop down to the stock of impact. While the backward and side will experience no breakdown. There would be only a little though for the stock of being impacted. And it is very easy to replace the grinding rod on the bottom. However, as for hammer crusher, it presents dangling. So it is very easy to be breakdown for all sides. Compared with hammer board, it will be more serious. Its metal utilization can only reach 25percent and its rotor is very easy to be breakdown. While as for impact crusher, its metal utilization can reach 45 percent to 48 percent.

Impact crusher performs very effectively. When electromotor drives rotor spin, material go into hammer board section and collide with hammer board on the rotor, and then being crushed by thrown to counter-attack device. Repeat impact in the impact crusher can crush the stone into pieces as you expected. Impact crusher works well in a rather simple principle and low cost.
