This impact crushes materials with impact force. When the materials enter the blow bar area, they are crushed due to the high-speed impact of the blow bar and are thrown to the impact plates on the rotor for secondary crush. Then the materials will be shot back to the blow bar again for the third crush. This process will repeat until the materials are crushed to the required size and discharged from the lower part of the machine. The size and shape of the finished powder can be changed by adjusting the gap between the impact rack and rotor support. The machine employs self-weight security device in its back frame. When other objects enter the impact cavity, they will be forced out of the machine by the impact rack in the front and back of the machine.

Working Principle:

It consists of frame,eccentric shaft,jawstock,toggie plate,cheek plate(up and down),set adjustment,fixed and moveable jaw the toggie plate also play a role of security.
1) This jaw crusher uses motor as its power. Through the motor's wheels, the eccentric shaft is driven by the belt and the belt wheel to make the jawstock move by a regulated track.
2)The angle between the toggie plate and jawstock will become large as the up of the jawstock. This will push the moveable jaw plate towards the fixed jaw plate,which can realize the multi-crushing of the materials.
3)The angle between the toggie plate and jawstock will become small as the down of the jawstock. The moveable jaw plate will leave the jaw plate at the presure of the tension rod and spring ,meanwhile ,the final products will be discharged from the dischargeing opening.

Structure Features:

Impact Crusher features many advantages: simple structure, non-key connection, high chromium flat hammer, special impact plate, simplified crushing process, and high-efficiency and energy conservation, cubic shape for the final products ,as well as the convenient maintenance and reliable operation. The discharging opening can also be adjusted.
