How Impact Crushers Work: A Comprehensive Guide
Another advantage of using an impact crusher is that it has a relatively low operating cost. The machine uses less energy than other crushers, such as jaw or cone crushers, and its impact force is more efficient at breaking down the material, resulting in less energy waste. However, there are some limitations to the use of impact crushers.

A performance model for impact crushers
For comparison, when the model of Whiten and White (1979) is used for simulation of the behaviour of short-head cone crushers, the values for φ, m and l are often fixed to 0.2, 0.5 and 2.5 respectively. A greater value for the fine fraction φ in our case reflects the well-known fact that the product issued from impact crushing contains more fines than that obtained with cone …
