Jaw Crusher

Introduction:Jaw Crusher is a kind of stone crusher, and jaw crusher is also called rock crusher, tiger mouth. China jaw crusher is widely used to crush medium sized granularity of different ores and bully materials with compressive strength less than 250Mpa in mining. Therefore, jaw crusher is also called as limestone crusher, granite crusher and cobblestone crusher.

Jaw Crusher Overview

Hongji Mine Machinery PE jaw crusher is high efficient and energy-saving coarse crushing machine that absorb domestic and foreign advanced technology and are researched by combining the specific mining conditions of domestic sand and gravel industry. Because of its simple and robust structure, reliable operation, easy maintenance and low production and investment cost, PE jaw crusher and small jaw crusher are widely used in metallurgy, chemical industry, building materials, electric power, transportation and other industrial sectors, which is suitable for coarse, medium and fine crushing of various ores and rocks with compression strength not more than 147-245 MPa.

Jaw Crusher is a kind of stone crusher, and jaw crusher is also called rock crusher, tiger mouth. China jaw crusher is widely used to crush medium sized granularity of different ores and bully materials with compressive strength less than 250Mpa in mining, metallurgy, building materials, highway, railway, water conservancy and chemical industries.Therefore, jaw crusher is also called as limestone crusher, granite crusher and cobblestone crusher.

The performance characteristics of jaw crusher

1. The crushing cavity of jaw crusher is deep and has no dead zone, which improves the feeding capacity and productivity.

2. Big reduction ratio and even product granularity.

3. There is an adjustable device of gasket discharging opening, which is reliable and convenient and which has large adjustable range and improves the flexibility of equipment.


4.Reliable and safe lubrication system. The replacement of spare parts is convenient and the maintenance workload is small.

5. This PE jaw crusher for sale has the advantages of simple structure, reliable operation and low operating costs.

6. Hongji small jaw crusher machine can save energy about 15%30% because its double energy saving system.

7. The adjustable range of discharging port of Fote small crusher is large, which can meet the requirements of different customers.

8. Low noise and dust.

Working principle of jaw crusher

The jaw crusher adopts crank link mechanism. 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 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.
