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 metal piece.

Jaw crushers, occasionally referred to as "toggle crushers," are the most common type of crusher. Material is compressed between a moving piece of steel and a stationary piece. Cone crushers are compression crushers that use a rotating piece of steel against a stationary piece of steel to reduce material. While similar in design and ...
