Jaw crusher crushing method for the song squeeze type, the working principle of the main simulation of animal movement of the two jaws. When working, the motor drives the belt and the pulley, moves the movement jaw up and down through the eccentric shaft. When the moving jaw rises, the angle between the brackets and the moving jaw becomes larger, so as to push the moving jaw plate close to the jaw plate, the material through the two jaws between the extrusion, rubbing, grinding and so on to achieve multiple crushing; when the moving jaw down, the brackets and moving jaws between the smaller angle, moving jaw plate in the rod, the role of the spring to leave the jaw plate , Has been broken material under the action of gravity, the jaw cavity at the lower part of the discharge port free discharge. With the continuous rotation of the motor, moving jaw to do the cycle of crushing and nesting, to achieve mass production.
