Jaw crusher application
Jaw crusher is widely used in many industrys including Mining,  Construction, Quarry, Ore, Stone, Chemical Industry, Metallury, Building Materials, Highway, Road  and so on.
It is suitable for the primary or secondary crush of large rock with compressive resistance no more than 320MPa. 
PE Jaw Crusher is used for primary crushing, and PEX jaw crusher is used for secondary and fine crushing.
Jaw crusher Features and our main advantages
 
1. Simple structure, easy maintenance, stable function, low operation cost, great crushing ratio. 
2. Deep crashing cavity, no unreachable corner in cavity, higher feeding capacity and productivity. 
3. Great crushing ratio, homogeneous output size. 
4. Discharging adjustment by shim, reliable and convenient, broad range of adjustment, more flexibility. 
5. Safe and reliable lubrication system, easy change spare parts, less effort in maintenance. 
6. Simple structure, reliable work, low cost in operation. 
7. Less energy consumption: one machine can reduces 15%-30% energy consumption, and the whole system can reduces by a half. 
8. Discharging sizes can adjustment to meets variable requirement of customers. 
9. Low noise, little dust.

Our Advantages
1.  Jaw Plate and side plate
Jaw crusher have 1pc mobile jaw plate, 1pc fixed jaw plate, 2pcs side plate, when crushing material, this 4 parts directly touch and crush the raw material.
Our jaw plate and side plate is made of High Manganese steel Mn13Cr2, Mn13Cr2 is a high wear-resistance material, which can prolong the service life of the machine. In case of hard pebble stone, it can crusher 20000 tons stone.
2.Toggle Plate
Insurance toggle plate adopt special material, when need break it will break, no need break will never break.
3. Eccentric Shaft
The eccentric shaft after tempering process is very endurable.
The upgrade large diameter shaft will suit heavy duty crushing work.
4. Frame
Casting Frame
Small and middle model jaw crusher adopt Heay-duty and thick durable design casting frame.
Welding Frame
Middle and big model jaw crusher adopt GB steel plate weld.
5. Main Shaft and Bearing
Main shaft through dynamic balance testing, our jaw crusher bearing is Swedish SKF bearing.
6. Motor
China famous brand motor,motor warranty 3 years.
7. Spring
High Strength spring adjusted well discharging sizes.
8. Our machine delivery with chassis, can install the motor or diesel engine.
9. Jaw crusher can installing tyre easy mobile and installing vibrating screen get different ideal sizes.

Jaw Crusher Working Principle:

The motor drives the belts and the belt wheels, and make the movable jaw up and down by the eccentric shaft. When the movable jaw descends, the angle between the fixed jaw and the movable jaw becomes smaller, and the materials can be crushed; when the movable jaw rises, the angle between the fixed jaw and the movable jaw becomes bigger; and the movable jaw plate leaves from the fixed jaw by the function of the tension rod and the spring. And then the crushed materials are discharged from the lower outlet of the crushing cavity.
