The Development of Impact Crusher

Of the five crushing machinery series, both impact crusher and hammer crusher crush brittle materials mainly by impact action, so they are often called impact crusher. Compared with jaw crusher, cone crusher and roll crusher that crush materials mainly by squeezing action, impact crusher has the following features:

A. High crushing ratio. The crushing ratio of impact crusher can reach over 50, while it is difficult for jaw crusher, cone crusher and roll crusher to exceed 20. So impact crusher is widely used in the industry where the single-stage crushing is required, such as the limestone crushing in cement industry.

B. Good product particles. Under the influence of impact action, the crushed materials often crack in its most fragile surface. The selectively crushing method ensures higher probability of cubic product particles, the final product of impact crusher in needle flake can be less than 10%, while for jaw crusher, cone crusher and roll crusher, the final product in needle flake will be higher than 15%. Therefore, impact crusher is often used as the final crushing equipment to produce concrete aggregate in the industry where cubic product particles is required, such as the anti-skid surface in high-grade highway.
