Structure
The lab jaw crusher is mainly composed of frame, fixed jaw plate,movable jaw plate, left and right guard plates, movable jaw, eccentric shaft,toggle plate, adjustable base, adjustable screw stem, adjustable wedge block, fitting of tension spring and so on.
Working Principle
When the jaw crusher is working, 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.
