Introduction to Jaw Crusher Equipment. Jaw crushers are a type of rock crusher that uses a fixed jaw and a moving jaw to crush materials.The fixed jaw is stationary and acts as a support for the moving jaw, which pivots on an eccentric shaft. This motion causes the crushing chamber to open and close, crushing the material between the two jaws.
