Jaw Crusher

Jaw Crusher Introduction

Jaw crusher machine is a kind of machine used for crushing ore, and the crushing process is to put mechanical force on solid material and overcome cohesive materials, for breaking materials into small pieces.

 According to the size of crushed materials, PE jaw crusher machine can be divided into coarse crushing, secondary crushing and fine crushing three types, and coarse crushing means primary crushing. Jaw crusher is also known as primary crushers or primary jaw crusher because it is often used as primary crusher.

Jaw Crusher Features

1. Simple structure, easy maintenance;
2. Large crushing ratio, uniform particle size;
3. Stable performance, low cost;
4. Low noise, less dust.

Jaw Crusher Working Principle

1. The dynamic jaw moving from side to side is hung on the mandrel. When the eccentric shaft is turning, its connecting rod moves up and down, which also drives the two thrust plates to do the same movement. Then the dynamic jaw moves from side to side to realize crushing and unloading.

2. The PE jaw crusher machine adopts crank link mechanism. Although the dynamic jaw bears great broken counter-force and the eccentric shaft and the connecting rod bears little stress, industrial enterprises usually make large sized machine and middle sized to crush hard materials.

3. Additionally, every moving track of the dynamic jaw is an arc with the mandrel as its center. The circular arc radius equals the distance from the point to the axis with the upper arc being smaller and the lower arc bigger. The crushing efficiency of the jaw crusher machine is quite high and the crushing ratio is 3-6.
