Jaw Crusher

Introduction of Jaw Crusher :

Jaw Crusher is a kind of stone crusher, and jaw crusher is also called rock crusher. Jaw crusher is widely used in many departments including Mining, Smelt metal, Building materials, Public road ,Railway, Water conservation ,Chemical industry and so on .

Our jaw crusher machine is developed based on many years of product development. The continuous improvement and refinement has made them the preferred Primary jaw crusher among professionals. This series of stone jaw crushers are divided into 11 models which can meet most capacity requirements in primary crushing and secondary crushing, with low power consumption and easy maintenance. Every feature of these primary crushers has been carefully designed to provide superior quality and performance. They are widely applied in areas of mining, metallurgy, construction, smelting, hydraulic and chemical industries, etc. Among this series of stone jaw crushers, large and medium-size stone jaw crushers are our competitive products; especially in designing and producing large-sized jaw crusher, we have already ranked the first place in China jaw crusher and foreign jaw crusher market.

Features and fuctions of Jaw Crusher :

1. The cavity of jaw crusher is deep and no dead area, so it prompts the feeding capacity and output.

2. The size of the reduction ratio is big and the production size is even.

3. Adjustment device of the spacer style discharge mouth is convenient and reliable. And jaw crusher's adjustment range is big what improves the flexibility of equipment.

4. Lubrication system of jaw crusher is safe and reliable. Unit replacement is convenient. And the work of maintenance is small.

5. Its structure is simple and operation is reliable. The operation charge is low.

6. Energy conservation : single machine's energy conservation 15%-30% and the machine system energy conservation is more than twice of the single machine.

7. The adjustment range of the outlet is big, so it can satisfy the requirement of different customers.

8. The noise of jaw crusher is low and dust is little when jaw crusher works.

Working principle of Jaw Crusher :

The main structure of the Jaw Crusher are composed of stander, eccentric shaft, belt pulley, flywheel, movable jaw plate, wrist plate ,adjustable gap screw, offsetting spring, fixed jaw plate. The wrist plate also has the effect of guarding.

This Jaw Crusher's crushing style is the type of driving extrusion. The motor drives the belt and belt pulley to make the moveable jaw move through the eccentric shaft. When movable jaw is rising ,the included angle between the wrist plate and movable jaw become bigger to drive the movable plate to be close to the movable plate. At the same time the material is squeezed and rubbed, rolled to achieve multiple crushing;

When movable jaw is descending, the included angle between the wrist plate and movable jaw becomes smaller. Now the crushed material is discharged from the crushing cavity, with the continuous rotation of the motor, the movable jaw crushing and discharging the material periodically to realize batch production.
