Jaw crusher

 1. Brief Introduction

Jaw crushers are typically used as primary crushers, or the first step in the process of reducing rock, are 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). They crush primarily by using compression, is widely used in mining, metallurgy, construction, highway, railroad, and chemistry industries. Our company's products are used of high-strength manganese steel, a shape casting, with advantages of wear-resistant, resistance, long life and so on. They main application for breaking large, medium and small stones and corresponding objects.

2. Jaw crusher features :

1, World-class skills in making are adopted and the use of high-tech materials.2, More advanced movable jaw assembly makes it more long-lasting.Movable jaw assembly adopts a high-quality steel casting, and moves through two large cast steel flywheel drive. In addition, heavy eccentric shaft has also adopted forging billet for processing. All those make the PEW series of jaw crushers with exceptional reliability.3, Integrated Cast Steel Structure Adopted in Axle Bearing housing.Integrated cast steel structured axle bearing housing can guarantee to be perfectly cooperating with the crushing frame. Meanwhile, it greatly enhances the intensity of the axle bearing, which could not be performed in the separated styled axle bearing.4, Use of finite element analysis technology makes the crusher with high intensity.5, Summarized structure “V”adopted in the crushing cavity makes the actual feed mouth width equal to the set width of the feeding opening.6, More quickly and convenient adjustment at the discharging opening.European styled PEW series of Jaw Crushers are equipped with wedge adjustment devices, which is simpler, safer and faster than former gasket devices. 

3. Jaw crusher work principle:

The motor transmits power through belt, drives the moving jaw do periodic motion to the fixed jaw surround the eccentric shaft. The angle between toggle plate and moving jaw increases when moving jaw moves up. So the moving jaw closes to the fixed jaw. The stuff will be crushed in this process. The angle of Jaw Crusher between toggle plate and moving jaw decreases when moving jaw moves down, the moving jaw of Jaw Crusher moves away from fixed jaw by the pulling of rod and spring, the products after crushing will be discharged from the outlet of Jaw Crusher.
