cost of one set of the mill's replacement parts. Consider, for instance, a 100-horsepower hammermill that grinds corn. The cost of the mill's replacement parts breaks down to $0.01 to $0.05 per ton of ground corn, and the mill's energy cost per ton is $0.50 to $1.40. When the mill has a new screen, hammers, and pins, it yields 15 tph

Impact Crusher Working Principle

Starting from the base working principle that compression is the forcing of two surfaces towards one another to crush the material caught between them.Impact crushing can be of two variations: gravity and dynamic. An example of gravity impact would be dropping a rock onto a steel plate (similar to what goes on into an Autogenous Mill).
