Working Principle
The main structure of lab jaw crusher: frame, eccentric shaft, big pulley, flywheel, side guard ,elbow board, elbow board seat, adjusting screw rod, the return spring, fixed board and adjusted jaw board, and the elbow board can play a role as Protector. The broke drive model of this series jaw crusher is curved extrusion. Motor-driven belt and pulley, through the eccentric shaft to let the jaw up and down, when the movable jaw rises bracket, and the angle Motor-driven belt and pulley, through the eccentric shaft to move jaw up and down movement, when the movable jaw rises, the angle between elbow board and movable jaw plate becomes larger, thus promoting the movable jaw plate close to the fixed jaw plate, while the material can be crushed by squeezed, rubbing, grinding. When the movable jaw fall down, the angle between elbow board and movable jaw becomes smaller, the movable bard will leave the fixed jaw board by the action of rod and spring, at the same time crushed material is discharge through crushing chamber.
