Jaw crusher type

According to the width of the feeding opening, jaw crusher is divided into three types: large, medium and small. The feeding opening width is greater than 600MM for the large jaw crusher, the feeding opening is 300-600mm for the medium jaw crusher, and the feeding opening is less than 300MM for the small crusher.

According to the different swing mode of movable jaw plate, jaw crusher can be divided into simple pendulum crusher, complex pendulum crusher and comprehensive swing jaw crusher.

Jaw crusher working principle

When the jaw crusher works, the electric motor drives V-belt to make the swing jaw up and down through eccentric shaft. When the swing jaw goes up, the angle between toggle plate and swing jaw gets bigger, and the materials can be crushed. When the swing jaw goes down, the angle between toggle plate and swing jaw becomes smaller, the swing jaw moves away from the fixed jaw plate, and then the crushed materials will be discharged from the lower outlet of the crushing chamber.

Jaw crusher features

1. Compact and simple structure, eccentric shaft and other transmission parts has less stress.

2. Due to the small vertical displacement of movable jaw, there is less excessive crushing of materials during processing, and the wear of movable jaw is less.

3. Jaw crusher has lighter weight, the component is less, the structure is more compact, the material is evenly crushed. 

4. The material block has a large up-and-down rolling motion in the lower part of the movable jaw, which is easy to be unloaded in the shape of a cube, reducing the flaky components, and the product quality is better.
