1. Technical support of jaw crusher

1) Symmetrical deep crushing chamber is adopted to maximize range of feed size,capacity and crushing ratio. 2) Three-dimensional software is adopted to optimize crusher parameters and parameter proportion,and reduce equipment self-weigth,so capacity is increased more than 30%. 3) Bearing seat of jaw crusher is designed integrally,so manufacturing dificulty is greatly reduced,and bearing life is increased. 4) There is a thick replaceable plate on the top of moving jaw to prevent moving jaw from being impacted. 5) Jaw crusher edge is adopted to replace traditional gasket,so the adjustment is much easier and more reliable.Discharging size can be adjusted into and size of the adjustment range.

 

2. Introduction of jaw crusher

Jaw crusher is one of the most popular equipment in mine industry production. It is mainly used in all kinds of materials with middle crushing or coarse crushing, and the crush resistance below 320MPa. Jaw crusher has the features of high crushing rate, simple structure, stable operation, easy maintenance and low operation cost. Jaw crusher is derived by motor through the motors wheels; the eccentric shaft is derived by the fangled belt and slot wheel to make the movable jaw plate move by a regulated track. Therefore, the materials in the crushing cavity composed of fixed jaw plate, The movable jaw plate and cheek plate can be crushed and discharged through the discharging opening.

 

3. Structure of jaw crusher

The main work parts of jaw crusher are composed of the fixed jaw plate and movabale jaw plate, The motor transmits power through belt, drives the moving jaw do periodic motion to the fixed jaw surround the eccentric shaft. The stuff will be crushed in this process . Jaw crusher is suitable to crush various kinds of ores and rocks of rough, medium hardness

 

4. Working principles of jaw crusher

Jaw crusher consists of frame, eccentric shaft, belt wheel, flywheel, movable jaw, side guard plate, toggle plate, toggle backseat, gap adjusting screw, returning spring, fixed jaw plate and movable jaw plate. Toggle plate is also used to guarantee the security. Jaw crusher uses electric motor as the motive power. Eccentric shaft is driven by triangle belt and genea wheel, which makes movable jaw make reciprocating motion according to the desired trajectory. Then, materials in crushing chamber (consists of fixed jaw plate, movable jaw plate and edge plate) are crushed and the finished materials are discharged from discharging hole

 

5. Application areas of jaw crusher

Jaw crusher is widely used in stone mining, metallurgy industry, building material, highway, railway, chemical industry, water conservancy mine, construction, traffic, energy and metallurgical divisions.

 

6. Features of jaw crusher

1).Jaw crusher is of high crushing ratio, big reduction ratio and uniform final product size; 2).Jaw crusher is of simple structure and low operation and maintenance cost;
3).Big adjustment range of the outlet of jaw cruher can satisfy the requirement of different customers;
4).Jaw crusher is of safe and reliable lubrication system, easily changed spare parts and easy maintenance;
5).Jaw crusher is of low noise and little dust pollution.

 

7. Factors to enhance jaw crusher

1) Proper selection of the jaws.
2) Proper feed gradation.
3) Controlled feed rate.
4.)Sufficient feeder capacity and width.
5) Adequate crusher discharge area.
6) Discharge conveyor sized to convey maximum crusher capacity.
