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.
How Jaw Crusher Crushes?
A Jaw Crusher is one of the main types of primary crushers in a mine or ore processing plant. The size of a jaw crusher is designated by the rectangular or square opening at the top of the jaws (feed opening). For instance, a 24 x 36 jaw crusher has a opening of 24" by 36", a 56 x 56 jaw crusher has a opening of 56" square. Primary jaw crushers are typically of the square opening design, and secondary jaw crushers are of the rectangular opening design. However, there are many exceptions to this general rule.
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 movable jaw exerts force on the rock by forcing it against the stationary plate. The space at the bottom of the "V" aligned jaw plates is the crusher product size gap, or the size of the crushed product from the jaw crusher. The rock remains in the jaws until it is small enough to pass through the gap at the bottom of the jaws.
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.
