High-Performance PE Series Jaw Crusher from China Suppliers and Factory for Primary and Secondary Crushing
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: What is the working principle of a jaw crusher?
A jaw crusher uses an eccentric shaft to drive a moving jaw up and down. When the jaw rises, the angle between the toggle plate and moving jaw increases, squeezing the material against the fixed jaw plate. As the jaw moves down, the crushed material is discharged from the bottom opening by gravity.
Q: What materials are PE series jaw crushers suitable for?
PE series jaw crushers are widely used for primary and secondary crushing of various minerals and rocks with a compressive strength not exceeding 320 MPa, such as granite, basalt, limestone, quartz, and iron ore.
Q: What is the difference between PE and PEX jaw crushers?
PE series jaw crushers are primarily used for coarse crushing with larger feed opening sizes, whereas PEX series jaw crushers are designed for secondary and fine crushing, featuring smaller feed openings and narrower discharge ranges.
Q: How do I adjust the discharge opening size of the jaw crusher?
The discharge opening can be adjusted by changing the thickness of the shim adjustment plates or using the wedge adjustment system located at the rear of the machine, which allows you to control the final output size.
Q: What are the main wear parts that require regular maintenance?
The main wear parts of a jaw crusher include the fixed jaw plate, moving jaw plate, toggle plate, side liners, and the eccentric shaft bearings. Regular inspection and lubrication of these parts will extend the service life of the machine.
