Our Large Industrial Rock Crushers employ two planer-crushing surfaces set at a small angle to each other and convergent downward. One plane is fixed and the other is pivoted either top or bottom allowing a reciprocating motion when pushed by a pitman-toggle arrangement activated by an eccentric drive. The 3 common variations of the jaw …
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.
