Crusher - Wikipedia

A jaw or toggle crusher consists of a set of vertical jaws, one jaw is kept stationary and is called a fixed jaw while the other jaw called a swing jaw, moves back and forth relative to it, by a cam or pitman mechanism, acting like a class II lever or a nutcracker. The volume or cavity between the two jaws is called the crushing...

Jaw crushers are used as primary crushers, or the first step in the process of reducing rock. They crush primarily by using compression. The rock is dropped between two rigid pieces of metal, one of which then moves inwards towards the rock, and the rock is crushed because it has a lower breaking point than the opposing...

40-to-1 in one processing pass. The cage mill's high size-reduction ratio results from its crushing mechanism: impact rather than compression. While a compression mill, such as a jaw or roll crusher, slowly applies the crushing force, an impact mill, like the cage mill or vertical shaft impactor, does so suddenly and quickly.
