How A Jaw Crusher Works

If you can explain how a nutcracker works you can essentially envision the operation of a jaw crusher.

Inside the chamber there are two jaws. One is fixed while the other constantly moves back and forth. This action compresses the rock causing it to break.

Rocks stay in the jaws until they are small enough to pass through the bottom gap.
