Jaw crusher is mainly used for medium crushing and fine crushing of raw materials. The crushing mode is curved extrusion type. It has the characteristics of large crushing ratio, uniform product particle size, simple structure, reliable operation, simple maintenance and economic operation cost. It is widely used in mining, smelting, building materials, highway, water conservancy, chemical industry and many other departments to crush all kinds of materials with compressive strength less than 320 MPa.

Jaw crusher has the following performance characteristics:

1. The crushing ratio of jaw crusher is about 15, and the particle size is uniform;

2. It has a large range of adjustment and reliable operation;

3. The jaw crusher has high production efficiency and low energy consumption. Compared with ordinary fine jawbone, the processing capacity of jaw crusher is increased by 20-35% and the energy consumption is reduced by 15-20%;

4. The crushing chamber of the crusher is deep and there is no dead zone, which improves the feeding capacity and output;

5. Under the same process conditions, the service life of jaw plate can be extended by more than 3-4 times, especially for high abrasive materials;

6. The lubrication system is safe and reliable, the parts are easy to replace, and the maintenance workload is small.

The jaw crusher is mainly composed of pull rod, spring, adjusting pad, adjusting seat, elbow plate, moving jaw, eccentric shaft, fixed wedge of moving jaw, moving jaw, side guard plate, fixed jaw plate, frame and other equipment. The crushing mode of PE Series jaw crusher is curved extrusion type. The belt and pulley are driven by motor, and the moving jaw moves up and down through eccentric shaft, When the moving jaw rises, the angle between the elbow plate and the moving jaw becomes larger, which promotes the moving jaw plate to approach the fixed jaw plate. At the same time, the material is crushed by extrusion, rubbing and grinding;

When the moving jaw goes down, the angle between the elbow plate and the moving jaw becomes smaller, and the moving jaw plate leaves the fixed jaw plate under the action of the pull rod and the spring. At this time, the crushed materials are discharged from the lower opening of the crushing cavity. With the continuous rotation of the motor, the crushing mobile jaw makes periodic crushing and discharging to realize mass production.
