How jaw crusher works?

Jaw Crushers are ideally suitable for primary and secondary crushing, with low power consumption and easy maintenance. Every feature of these machines has been carefully designed to provide superior quality and performance. Jaw crusher can be used with the ore dressing equipment or used independently. Jaw crusher can be used to produce the aggregate for subgrade, railway ballast and construction sand and stone. The jaw crusher is divided into the coarse jaw crusher and the fine jaw crusher, i.e. PE series and PEX series.

A jaw crusher reduces large size rocks or ore by placing the rock into compression, a fixed jaw, mounted in a “V” alignment is the stationary breaking surface, while the moveable jaw plate exerts force on the rock by forcing it against the fixed jaw plate. The space at bottom of the “V”, aligned jaw plate， is the crusher product size gap, or the size of the crushed product from the jaw crusher.
Due to the advantage of simple structure, reliable performance, convenient maintenance and safe use, our jaw crushers of various sizes are widely used in the crushing operation in metallurgy, mining, building materials, chemical industries and cement enterprises.

Working Principle:

The motor drives the mobile jaw up and down through eccentric shaft. The angle between toggle plate and mobile jaw increases when mobile jaw plate moves up. So the mobile jaw plate closes up the fixed jaw plate. The stuff will be crushed in this process. The angle between toggle plate and moving jaw decreases when mobile jaw moves down. The mobile jaw plate move away from the stationary jaw plate with the pull of draw rod and spring, so the crushed stone will be discharged from the outlet. This process will repeat. The moving jaw will crush and discharge the stuff circularly.
