Four Structure of Jaw Crusher

In this text, Luoyang Dahua will talk about the main structure of jaw crusher

1. Safety Device

Toggle plate of jaw crusher not only transfers the power, but also serves as the safety device. When the non-crushed materials enter into crushing cavity, the toggle plate firstly bends or twists the materials to protect the machine spare parts.

2. Rotation Parts

Jaw crusher is composed of swing jaw, eccentric shaft, bearing, and belt pulley, which are the main parts for driving and bearing torque.

a. Swing jaw: It is consist of swing jaw frame and swing jaw plate. The frame is made from 35# casting steel with thermal refining.

b. Bearing: Adapt double-row spherical roller bearing and has the feature of fine tune, large loading, and durable.

c. Eccentric shaft: It is made from 45# steel in the lathe with thermal refining.

d. Jaw plate: It includes swing jaw plate and fixed jaw plate. In order to improve the crushing effect, the plate surface with tooth that featured in high hardness, good wear-resistance and using effect.

3. Discharge Adjustable Device

It is used to adjust the discharge opening to control the discharge granularity. 

4. Fixing Device

Frame is the main part of fixing device, which has two processing technology: middle carbon casting steel frame and middle carbon welding steel frame.
