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, metallurgical industry, building material, highway, railway, and chemical industry.
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.
The motor drives the eccentric shaft to rotate by the V belt & the slot wheel, then the movable jaw moves back and forth to break the materials in the crushing cavity which is composed of fixed jaw plate & movable jaw plate and side guard plate. When the movable jaw rises, the angle between the fixed jaw and movable jaw gets larger, and the materials can be broken to reach the crushing target. When the movable jaw is moving down, the angle between the fixed jaw and movable jaw becomes smaller .the end products slide from the discharge opening at the bottom.
Application in mining
Jaw crusher is be widely applied in metallurgic, mining, chemical, cement, construction, refractory and ceramics industries, for the medium or fine crushing of various medium hard rocks and minerals, etc. The jaw crusher is capable to crush mineral ores, rocks, and slag with crush strength less than 280Mpa. And size of materials fed in the stone jaw crusher should be equal or smaller than the maximum feeding size described in the following technical data.
In the crushing line, the stone jaw crusher is usually used in the primary crushing. The stone crushed by the jaw crusher will be delivered to the impact crusher by belt conveyor. After crushed by the impact crusher, the crushed stone will be delivered to the vibrating screen. The finished product will be screened out. The stone bigger than the required size will be returned to the impact crusher for re crushing. It's a closed circuit.
