1. The crushing cavity
Crushing cavity is fixed on the rack on the fixed crushing plate and moving jaw of the activities of the crushing plate and frame on both sides of the wall of two side plate for a giant truncated cylinder up and down. After being broken material is feeding crushing cavity, through dynamic jaw movement, crushing cavity volume cycle change and complete material crushing and discharging.

2. The broken plate
In order to improve the crushing effect, both the surface of the crushing plate with a vertical corrugated, methods and relative. So, besides have crushed effect of minerals, and bending effect. Crusher work space on the sides of manganese steel lining plate is also, because of the broken plate wear is not uniform, particularly near the row ore mouth crushing plate bottom wear is the largest, therefore, are often made up and down the broken plate relative, convenient and lower wear, would be the inverted the reuse.
3. The moving jaw
The motion of the moving jaw is borrow the crank rocker mechanism to crank the double rocker mechanism by the eccentric shaft, connecting rod, the former of the thrust plate and thrust plate. Eccentric shaft in the frame on the wall of main bearing and connecting rod is installed on the part of eccentric shaft, before and after the thrust plate at one end of the support on the floor of the connecting rod head on both sides of the groove, the former after the moving jaw thrust plate at the other end of the supporting wall bottom floor of the seat, and then the other end of the thrust plate, bearing wall after the rack is woven of iron on the floor. When eccentric by pulleys from motor rotation, makes the connecting rod moves up and down. Connecting rod moves up and down and drive the thrust plate movement. Due to the thrust plate changing Angle, thus make the moving jaw around the eccentric shaft.
4. The connecting rod, a spring
When connecting rod downward movement, to make the moving jaw, regular contacts between the thrust plate and the connecting rod, and USES the two pull rod and two spring tension device consisting of a rod hinged between the lower jaw, the other end with a spring supported on the lower end of the rack back wall when the moving jaw forward swing rod through the spring balance jaw movement and inertia force produced by the thrust plate.
Its working principle: Jaw crusher working principle is through the eccentric shaft, the motor drive belt and pulley to move up and down movement of hubei. In hubei rises, bracket and dynamic Angle increases gradually, the question of hubei to hubei board gradually pushing to the fixed jaw position, at the same time the material will be crushed or broken problem, so as to achieve the broken effect. When moving downward of hubei, the Angle between the bracket and dynamic hubei will further smaller, tie rod and the action of the spring on the moving jaw plate, would leave and fixed jaw plate, at this point has been broken material from crushing cavity mouth out.
