Jaw Crusher is ore crushing equipment for hard materials, it has the features of high crushing ratio, yield, even granularity, simple structure, easy maintenance, and low production costs. When working, dynamic jaw plates of Jaw Crusher directly contact with the material, and often bear larger loads. When materials are fed into the crusher, there are often a special and strong blocks of stone or iron, such as broken objects, if there is no appropriate insurance against this situation in a timely manner, but malformation of the hard materials in the crushing cavity are crushed or even impede the operation of the device, and resulting in downtime reviewing.
