Structure of Jaw Crusher

This jaw crusher working theory is: The motor drives belt and belt wheel, the eccentric shaft causes the movable jaw to move down and up, forward and backward, the angle between toggle plate and movable jaw becomes bigger when the movable jaw moves up, so that the movable jaw moves toward the fixed jaw, and the materials are pressed, crushed, or cut, as a result, the aim of crushing is accomplished.

Working Principle of jaw crusher

The belt and belt pulley are driven by a motor, and the movable jaw moves up and down via eccentric shaft. The angle between fixed jaw and movable jaw becomes smaller when the moving jaw runs down, then the materials are crushed into pieces. It becomes bigger when the movable jaw runs up. The movable jaw plate leaves the fixed jaw plate under the action of tension rod and spring , then the end products come out from the crushing cavity.
