PEW Jaw Crusher, Expert of Open-pit Crushing Equipment

Adopting the world’s most advanced crushing technology, the PEW series jaw crusher can be considered as the expert of open-pit crushing equipment. It is another reliable machine used in open-pit mining by Zenith. As a professional manufacturer of open-pit mining equipment, Zenith never stop the exploration of producing more excellent crushing plants for open-pit mining. Nowadays, the PEW Jaw Crusher in European style undoubtedly becomes the most welcome equipment in the open-pit quarry. Our customers often choose it to deal with hard materials due to its high efficiency and reliable performance. We believe our jaw crusher will be proved as a reliable type of open-pit mining equipment. And it will play a great role in your open-pit quarry.

Brief Introduction of Zenith PEW Series Jaw Crusher

1.PEW series jaw crushers are mainly used in the metallurgical industry, mining industry, construction and chemical industry. They are used to making cement, building materials, fireproof materials and ceramics in the secondary and tertiary crushing, dealing with various hard minerals and rocks. 2. Materials (including minerals, rocks, slag) in open-pit mining is most suitable for this series of jaw crusher, the anti-pressure of which is no more than 280Mpa. In addition, the feeding size of materials should be no larger than the specification provided by our experts. Or it will bring great harm to your crushing plants.

Working Principle

Through the motion of triangle belt, the flywheel is driven by the motor. Then the flywheel drives the eccentric shaft to make the jaw plate do reciprocating motion. Materials will be crushed when the jaw plate move towards to the fixed jaw plate. End products will be discharged through the discharging opening when the jaw plate moves backward.

Unique Features

1. World-class manufacture crafts and high-tech materials are adopted in the production, which makes this series of jaw crusher are in line with the features of open-pit mining situations. 2. Advanced movable jaw assembly makes it more long-lasting. Movable jaw assembly adopts a high-quality steel casting, and moves through the two large flywheels made of cast steel. In addition, heavy eccentric shaft also adopts the forging billet when processing materials. All those new changes make the PEW series jaw crushers with exceptional reliability. 3. Integrated structure of steel casting is adopted in the bearing housing, which can guarantee a perfect cooperation with the crushing frame. Meanwhile, it greatly enhances the intensity of the axle bearing. 4. The technology of finite element analysis makes the crusher with high intensity. 5. The “V” structure is adopted in the crushing cavity, which makes the actual width of feeding open equal to the set width. 6. Quick and convenient adjustment at the discharging opening. Zenith PEW series jaw crushers are equipped with wedge-like adjustment devices, which are simpler, safer and faster than former gasket devices. 7. Chosen bearings are larger with better carrying capacity. Compared with the same specification of crushers, all PEW series jaw crushers are equipped with greater and more durable eccentric shaft bearings. The better capacity and more effective labyrinth seal greatly extend the service life of the bearings. 8. The newly-adopted tooth-boards have greatly increased the effective length of the jaw, resulting in larger yield.
