Its performance characteristics are large crushing ratio, uniform product size, simple structure, reliable performance, easy maintenance and low operating cost. Jaw crusher is usually used to crush materials during production and processing.

[0003] The existing jaw crusher drives the eccentric shaft to rotate through the driving module, drives the two thrust plates to do reciprocating motion, and thus drives the movable jaw to do left and right reciprocating motion to achieve crushing and unloading. When adding materials into the jaw crusher, the materials are usually poured directly into the jaw crusher, which will cause the poured materials to concentrate at a certain position inside the jaw crusher, making it impossible for the jaw crusher to crush the materials quickly and evenly.
