Introduction to Jaw Crusher

Jaw crusher is often used for primary crushing and secondary crushing, and can be used to crush all materials with a compressive strength below 320Mpa, such as basalt, granite, marble, limestone, etc. The jaw crusher is mainly composed of the frame part, the eccentric shaft rotating part, the crushing cavity working part, the safety device, the discharge outlet adjustment device, etc.

The working principle of the jaw crusher is that the motor is used as the power source. The motor inputs power to the pulley through the V-belt. The pulley drives the eccentric shaft to rotate to drive the movable jaw body to swing back and forth up and down.
When the movable jaw plate moves closer to the fixed jaw plate, the volume of the crushing cavity decreases, and the materials in the crushing cavity are squeezed or chopped. When the movable jaw plate moves away from the fixed jaw plate, the volume of the crushing cavity becomes larger. The broken small pieces of materials are discharged from the discharge outlet, which makes continuous circular motion to realize the crushing operation.
