What is a Jaw Crusher?

From sedimentary rock, granite, and basalts to concrete waste, glass, and other brittle materials, the overhead eccentric jaw crusher is the most widely utilized primary crushing system.

A jaw crusher is a compression machine. It consists of 2 corrugated jaw plates (dies), one fixed (stationary) and one that is movable.  The opening is wider at the top than the bottom.  Shot rock type material up to 90% of the jaw opening size is typically acceptable. With material like gravel, 80% size is encouraged. As material moves from the top of the chute to the bottom, it is crushed smaller and smaller until it finally passes through the opening at the bottom. You can change the size of the material by adjusting the final discharge setting of the jaw crusher.

Jaw crushers can be stand-alone, skid-mounted, or used on a variety of mobile and portable plants. They can be driven by an electric or hydraulic motor. They come in many sizes to fit a variety of applications.
