The jaw crusher is mainly used as a coarse crusher and a medium crusher in mining, building materials and infrastructure. According to the width of the feed inlet, it is divided into three types: large, medium and small. The one with feed inlet width larger than 600MM is large jaw crushers. The one with feed inlet width is 300-600MM is called medium-sized jaw crusher. The one with feed inlet width less than 300mm is called small-sized jaw crusher. The jaw crusher is simple in structure, easy to manufacture and reliable in operation.
The working part of the jaw crusher is two jaws, one is a fixed jaw (fixed), fixed on the front wall of the body, and the other is the movable jaw (moving), forming a large and small crushing cavity (working cavity) with the fixed jaw. The movable jaws periodically reciprocate against the fixed jaws, sometimes separated and sometimes close. When separated, the material enters the crushing chamber, and the finished product is discharged from the lower portion; when it is close, the material between the two jaws is crushed by bending, bending and splitting.
We can also configure the whole jaw crushing line as follows:
