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

Q: How does the PE Series Jaw Crusher work?

The motor drives the belt and pulley, moving the jaw up and down via an eccentric shaft. When the moving jaw rises, materials are crushed between the moving and fixed jaw plates. When it moves down, the crushed material is discharged from the lower opening.

Q: What is the maximum feeding size for these jaw crushers?

The maximum feeding size depends on the model. It ranges from 125 mm for smaller models like the PE-150×250, up to 1020 mm for heavy-duty models like the PE-1200×1500.

Q: How can I adjust the discharge opening size?

The discharge opening can be adjusted within the specified range (e.g., 10-40 mm or up to 150-300 mm depending on the model) using the adjustment system to control the output product size.

Q: What materials are suitable for crushing with the PE Jaw Crusher?

It is widely used for primary and medium crushing of various minerals and rocks with a compressive strength of less than 320 MPa, such as granite, basalt, limestone, and iron ore.

Q: How do the spring and pulling bar function in the machine?

The pulling bar and spring pull the moving jaw plate away from the fixed jaw plate when the jaw moves downward, ensuring the crushed material falls out smoothly and periodically.
