The jaw crusher ( jaw crusher) has the characteristics of large crushing ratio, uniform product size, simple structure, simple maintenance and economical operation. Jaw crusher is used in mining, building materials, chemical, metallurgical and other industries. It can be used for coarse and medium crushing operations on various ores, rocks and other materials with a compressive strength of not more than 320 MPa. It is used in ore crushers, coal gangue crushers, etc. The ore material is broken.

Jaw crushers are mainly used as coarse crushers and medium crushers in mining, building materials and infrastructure. According to the width of the feed port, it is divided into three types: large, medium and small. The feed port width is larger than 600MM for large machines. The feed port width is 300-600MM for medium-sized machines. The feed port width is less than 300mm for small-sized machines. machine. The jaw crusher has a simple structure, is easy to manufacture, and is easy to use and maintain.

The working part of the jaw crusher is two jaws, one is a fixed jaw (fixed), the vertical (or the upper end is slightly inclined) fixed on the front wall of the body, and the other is the movable jaw (moving), the position Tilting, 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 close, the material contained between the two jaws is crushed by bending, bending and splitting.

The jaw crusher can be divided into a simple swing jaw crusher (simplified pendulum jaw crusher) according to the different swinging modes of the movable jaw. There are three kinds of complex swing jaw crusher (complex pendulum jaw crusher) and integrated swing jaw crusher.
