Jaw Crusher is mainly used to crush kinds of mining stones primarily, and the largest compression resistance of the material to be crushed is 320MPa. The jaw crusher is widely used in mining, metall-urgical industry, building material, highway, railway, and chemical industry. Working Principle of Jaw Crusher: 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. Characteristics of Jaw Crusher: High ratio of crushing, homogeneous final grain size, simple structure, reliable working condition, easy maintenance, low operating cost. standard packing
