features

1. High qualified raw material, less wear, high productivity under any circumstances. Top manufacturing process is the basis for extraordinary machine.
2. Strong product commonality can reduce cost. Two-cavity impact crusher can becomes three-cavity machine by adding grinding racks, and no need to change other parts.
3. Heavy type rotor, finite element endurance analysis, optimized design, reasonable structure and enhancing moment of inertia lead to bigger crushing ratio and better abrasion resistance.
4. Static and dynamic balancing test for the welding rotor should be done before assembling. To make sure the rotor have a smoothly running and long working life.
5. Main shaft is finished by quality forging, adopts keyless design and world advanced cover tightening connection to ensure the reliable working and make the maintenance easier.
6. Unique locking device for hammers makes the tightening moment of force more safe and bigger. And the replacement of hammers can be more simple and convenient.
7. Standard design for liners increase the interchangeability, decrease the repertory and variety of liners.
8. Simple but practical locking device lock the shell 1 and shell 2 together. This device has a easy operation and saves locking time.
9. Unique hydraulic device design is convenient for opening the fame racks to replace wear parts and adjust the discharge size.
10. Simple structure for impact racks and grinding racks. Easy operation, long working life, convenient maintenance and low cost.

working principle

Impact crusher crushing material s with impact force.

When materials enter, 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 materials will be shot back to the blow bar again for the third

crush. Process repeats until the materials are crushed

to the required size and discharged from the lower part of the machine. Size and shape of the finished powder can be changed by adjusting the gap between the

impact rack and rotor support. Impact crusher employs self-weigh 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.
