Jun 23, 2015 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. dynamic impact could be described as material dropping into a rapidly turning rotor where it receives a smashing blow from a hammer or impeller.
Milling machine operation
Ag/sag mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill. because of the range of mill sizes available, ag/sag milling can often be accomplished with fewer lines than in a conventional rod mill/ball mill circuit. a diagram of types of ag/sag impact crusher.
