cycle. The primary crusher is the link between chemical comminution (blasting) and the beginning of the mechanical comminution circuit (crushing and milling). The primary crushers take blasted, run-of-mine, or run-of-quarry feed up to 1500 mm and produce a product ranging in size from -300 mm for conveyor transport, or -200 mm for SAG mill feed.

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).
