Product Description
PEW series Jaw Crushers are widely used in mine, building materials, chemical industry, metallurgy, whose compressive strength is below 320Mpa. Jaw Crushers, as the first choice of primary crushing, can be divided into coarse crushing and fine crushing with world-wide advanced technology.
The features of PEW jaw crusher:
1. World-level manufacturing technology is adopted, and highest-level raw material is used.
2. Central lubricating device are installed on the machine, so the bearing is easy to be lubricated.
3. Adjustment of the discharge part is more convenient.
The adjustment methods: gasket adjustment, hydraulic assistant adjustment, wedge block and wedge hydraulic adjustment.
4. More advanced movable jaw assembly lengthens life of crusher.
Movable jaw assembly is made from cast piece with high-quality, is driven by two large flying wheels which are made from cast steel. Moreover, heavy eccentric shaft is processed by forged mold. These entire make the PEW series jaw crusher extremely reliable.
5. Integral cast steel structure is adopted for bearing seat. Integral cast steel bearing matches well with the crusher frame, at the same time, radial strength of the bearing seat is highly strengthened.
6. Finite element analysis technology is adopted to make the crusher much stronger.
7. Crusher chamber adopts "V" structure which could make actual feed width comply with the nominal one.
8. Bearing with larger model and higher load are used.
All PEW jaw crusher is equipped with larger bearing compared with same model of normal jaw crusher. Its higher load capacity and effective oil seal will lengthen the life of bearing.
9. A newly designed tooth-shape side plate, makes the available area of jaw plate longer, and enhances the capacity.
10. Pressing bar and support type are used to fix jaw plate.
11. Heavy type protecting plate is installed for bearing seat, accidental damage of bearing seat is avoided.
12. Supporting bar under jaw plate protects movable jaw and frame from being worn down. rate bearing seat does not have this advantage.
Working Principle of PEW Jaw Crusher
The motor transmits power through belt, drives the moving jaw to do periodic motion towards the fixed jaw by the eccentric shaft. The angle between toggle plate and moving jaw plate increases when moving jaw moves. So the moving jaw moves towards the fixed jaw. The stuff will be crushed in this process. The angle between toggle plate and moving jaw decreases when moving jaw moves down, the moving jaw moves leaves fixed jaw by pulling rod and spring, the final crushed stuff will be discharged from the outlet.
