jaw crusher bearing temperature limit and failure solution

A Detailed Overview of Cone Crushers and What You Need to Know

What is a Jaw Crusher? Jaw crushers are a compression crusher that uses a set of jaws to crush aggregate materials. This machine features a fixed jaw and a moving jaw, oriented in a V position. Once you load material into the crusher, the movable jaw pushes material into the fixed jaw until it's crushed to the desired size.
