What Is A Jaw Crusher
All jaw crushers feature two jaws: one of which is fixed while the other moves. The working principle of jaw crushers is based on the reciprocating movement of the movable jaw that compresses and crushes the rock or ore between itself and the fixed jaw, as the material enters the zone between the jaws.

Primary Crusher vs. Secondary Crusher: Understanding Their …
— The jaw crusher works by moving the material between a fixed and a moving plate. The moving plate applies force to the material, causing it to break down into smaller pieces. The gyratory crusher, on the other hand, uses a mantle and concave surfaces to compress the material. The mantle is located above the concave, and as the mantle …
Jaw Crusher: Range, Working Principle, Application
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.
