Product Detail

Working Principle

Motor drives belt and belt pulley, makes moving jaw up and down through eccentric shaft. When the moving jaw is up, the angle between lining plate and moving jaw becomes large, and this will push moving jaw plate close to the fixed jaw plate. During this process, the material is crushed and ground, thus the crushing will be done. When the moving jaw is down, the angle between lining plate and moving jaw becomes small, the moving jaw plate will leave the fixed jaw plate on account of the effect of pulling bar and spring, and then the crushed material will be discharged from the lower opening of the crushing room. With the motor continuously rotating and the material periodically crushed and discharged by the crusher, the mass production can be realized.

Frequently Asked Questions

How does the PE Series Jaw Crusher work?

The PE series jaw crusher operates on a compression crushing mechanism. A motor drives the eccentric shaft via a belt and pulley system, causing the moving jaw to move up and down. When the moving jaw rises, the angle between the toggle plate and the moving jaw increases, pushing the moving jaw plate close to the fixed jaw to crush the material. When the moving jaw moves down, the crushed material is discharged from the lower opening.

What is the maximum feed size for the PE-600×900 model?

The maximum feeding size for the PE-600×900 jaw crusher is 500 mm, with a size of feed opening of 600×900 mm and a capacity range of 60-160 t/h.

How is the discharge opening adjusted on a jaw crusher?

The discharge opening is adjusted using the wedge adjustment system or shim adjustment mechanism located at the rear of the crusher frame. This allows users to control the size of the output materials according to their processing requirements.

What materials are suitable for crushing with the PE series?

The PE series jaw crusher is designed for primary crushing of hard materials. It is widely used to crush rocks, minerals, and ores with compressive strength below 320 MPa, such as granite, basalt, limestone, and quartz.

What maintenance is required for optimal jaw crusher performance?

Key maintenance practices include regular lubrication of the eccentric shaft bearings, monitoring the wear of the jaw plates and toggle plates, checking the tension of the pull bar and spring, and ensuring all bolts and connections remain tightly secured.
