Jaw Crusher

Brief introduction

Jaw crusher is mainly used to crush a variety of ores and material-grained bulk material, and it can coarsely or finely break materials with compressive strength not more than 320 Mpa. Jaw crusher is mainly used in mining, metallurgy, building materials, highway, railway, water conservancy, chemical and other industries. Medium-size jaw crusher is one of our company's leading products.

Application of stone jaw crusher: 
Jaw crusher is a kind of heavy duty machine which can crush materials into even granularity. This crushing machine has the characteristics of high reduction ratio, high productivity, simple structure, and reliable performance, etc. It is convenient to maintain and practical to use. Our Jaw crushers can be used in mining industry, metallurgical industry, construction, smelting, road building, chemical industry, and other fields, for crushing various materials whose compressive strength is not more than 320 MPa. 

Features of stone jaw crusher: 
1. Crushing chamber is deep and has no dead space, which helps improve the feeding capacity and productivity. 
2. Our jaw crusher has high reduction ratio and the crushed materials are of the even granularity. 
3. Adjustment device of gasket type discharging opening is reliable and convenient to use. The discharging opening has wide adjusting range. This can increase the flexibility of our equipment. 
4. Lubrication system is safe and reliable. Accessories are convenient to replace, and little maintenance is needed. 
5. Jaw crusher has simple structure, reliable performance and low operating cost. 
6. Jaw crusher is a kind of energy saving equipment. Single machine can save 15% ~ 30% energy and whole system saves more than doubled energy. 
7. Discharging opening has large adjusting range, so your different requirements can be satisfied. 
8. Low noise and little dust. 

Working Principle of stone 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.
