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). Dynamic impact could be described as material dropping ...

Crusher - Wikipedia

A cone crusher breaks rock by squeezing the rock between an eccentrically gyrating spindle, which is covered by a wear-resistant mantle, and the enclosing concave hopper, covered by a manganese concave or a bowl liner. As rock enters the top of the cone crusher, it becomes wedged and squeezed between the mantle and the bowl liner or concave. Large pieces of ore are broken …

06/06/2018· Sometimes the extent of this breakage is significant, such as in crushers and mills, which are designed to crush chunks of ore into smaller pieces. Breakage is insignificant in cases when particles are subjected to handling, mixing, compaction and separation operations, where breakage is not desired. However, in all cases, conducting DEM simulations without accounting for breakage can lead to ...
