What is a jaw crusher?


Jaw crusher is commonly known as jaw crusher, also known as tiger mouth. The crushing chamber is composed of two jaw plates, the movable jaw and the static jaw, and the crusher completes the material crushing operation by simulating the movement of the two jaws of animals. It is widely used in the crushing of various ores and bulk materials in mining and smelting, building materials, highways, railways, water conservancy and chemical industries. The maximum compressive strength of the crushed material is 320Mpa.

Jaw crushers are mainly used as primary and secondary crushers in mining, building materials, infrastructure and other sectors. According to the width of the feeding port, it is divided into three types: large, medium and small. The width of the feeding port is larger than 600MM is a large machine, the width of the feeding port is 300-600MM is a medium-sized machine, and the width of the feeding port is less than 300MM is a small machine machine. The jaw crusher is simple in structure, easy to manufacture and reliable in operation.
The working part of the jaw crusher is two jaw plates, one is the fixed jaw plate (fixed jaw), which is fixed on the front wall of the body vertically (or the upper end is slightly inclined outward), and the other is the movable jaw plate (moving jaw). It is inclined to form a crushing cavity (working cavity) with a large upper and a lower small with the fixed jaw. The movable jaw makes periodic reciprocating motion against the fixed jaw, sometimes separating and sometimes approaching. When separating, the material enters the crushing cavity, and the finished product is discharged from the lower part; when approaching, the material installed between the two jaw plates is crushed by extrusion, bending and splitting.

Jaw crushers can be divided into simple swing jaw crushers (simple pendulum jaw crushers) according to the different swing modes of the movable jaw plate. There are three kinds of complex swing jaw crusher (complex swing jaw crusher) and comprehensive swing jaw crusher.
