Overview
PEW Jaw Crusher is a new crushing machine, the jaw crusher manufacturer, after the release of traditional jaw crusher. This jaw crusher is a perfect combination of modern science and technology and the production practice, which can better satisfy the automatic production demands of vast customers.
European Type Jaw Crusher adopts world-class technology and high-end raw materials, which can crush hard stones or ores. Based on advantages of excellent quality, large output and long service life, this machine can be widely used in mining machinery, road, construction metallurgy, etc.
APPLICATIONS
1. This machine is mainly used in metallurgical industry, mining, chemical industry, cement, building, corhart and ceramics for medium crushing and fine crushing of mid-hard and hard stones.
2. This series crusher is suitable for mining stones and slag whose pressure strength is less than 280M Pa. The max. size of the raw material should not exceed the data in the following table.
Features
1. World-level manufacturing technology is adopted, perfect raw material is selected.
2. More advanced movable jaw assembly lengthens life of PEW.
Movable jaw assembly, composed of high-quality cast steel structure, is driven by two big flying wheels which is also made from cast steel. Moreover, heavy eccentric axle is processed by forge mold. All of these make the PEW series crusher extremely reliable.
3. 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. However, the separate bearing seat does not have this advantage.
4. Finite element analysis technology is adopted to make the crusher more stronger.
5. Crusher chamber adopts “V” structure which could make the actual feed width complies with the nominal one.
6. Adjustment of the discharge part is more convenient.
Discharge part of PEW series crusher is installed wedge block, which makes discharge more simple, safer and faster than the spacer on old style crusher.
7. Bearing with larger specification and stronger bearing capacity is used.
8. A newly designed tooth shaped jaw plate, makes the available area of jaw plate longer, and enhance the capacity.
Working Principle
Crushing way of this series jaw crusher is driving and grinding. The working principle is: The motor drives belt and belt wheel, the movable jaw plate moves by eccentric shaft. When movable jaw plate is driven by movable jaw towards fixed jaw plate, material is crushed or grinded.Motor drives the moving jaw up and down through eccentric shaft. The angle between toggle plate and moving jaw increases when moving jaw moves up. So the moving jaw closes up 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 move away from fixed jaw by the pulling of rode and spring, the stuff crushed will be discharged from the output opening. This process will repeat. The moving jaw will crush and discharge the stuff circularly.
