2019 Limestone Jaw crusher used for mining
Jaw Crusher (also known as tiger mouth) appeared in 1858. Jaw crusher widely used in mining, smelting, building material, highway, railway, water conservancy and chemical industry and many other sectors, broken less than 320 MPa compressive strength of various materials.
Advantages of Jaw Crusher
1. Heightened movable jaw assembly causes it to be more long-lasting. Movable jaw assembly adopts a high-quality steel casting, and moves through two large cast steel flywheel drive. Additionally, heavy eccentric shaft has also adopted forging billet for processing. All those increase the risk for PE jaw crushers with exceptional reliability.
2. Integrated Cast Steel Structure Adopted in Axle Bearing housing. Integrated cast steel structured axle bearing housing can guarantee being perfectly cooperating with the crushing frame.
3.Quicker and convenient adjustment on the discharging opening. Main structure adopted within the crushing cavity helps make the actual feed mouth width add up to the set width of the feeding opening.
Working principle of Jaw Crusher
The motor transmits power through belt, drives the moving jaw to do periodic motion towards the fixed jaw by the eccentric shaft. The angle between toggle plate and moving jaw plate increases when moving jaw moves. So the moving jaw moves towards the fixed jaw. The stuff will be crushed in this process. The angle between toggle plate and moving jaw decreases when moving jaw moves down, the moving jaw moves leaves fixed jaw by pulling rod and spring, the final crushed stuff will be discharged from the outlet.
