1. High-quality sheet metal and wear parts, reducing wear and tear, improve conditions of production efficiency; advanced processing technology and processes, is the basis of
2. equipment performance.
3. Product versatility, the two chamber crushing equipment in replacement of other parts of the foundation to increase the grinding holder, you can become a three-chamber ,crushing equipment, reduce user secondary investment.
4. Heavy-duty rotor, finite element stress analysis, optimal design, the structure is more reasonable, the moment of inertia of a larger, more broken than crushing capacity,
5. Rotor welding process, prior to assembly to be done to static and dynamic balance test, so that the rotor running more smoothly, use longer.
6. Spindle quality forgings finishing at the same time the whole shaft key design, using state-of-the-art international expansion sets up tight connection, more reliable equipment
7. Operation, post-maintenance easier.
8. Unique board hammer locking device, tightening torque larger, more secure, the board hammer replace it with a more simple, convenient and fast.
9. Lining standardized design, strong interchangeability, and to reduce the types of user spare parts and inventory, and replacement easier.
10. A simple and practical locking means, the Impact Crusher housing a housing two tightly locked together. Such device operation is simple, convenient, and the locking time
11. Unique hydraulic device design, both user-friendly easily open rack, replacement parts, and can adjust the discharge opening counterattack frame.
12. The counterattack rack and the structural adjustment of the grinding holder is simple, easy to operate, difficult to damage, at the same time easy maintenance, and low cost.

European Type Impact Crusher is a kind of crusher which crush the raw material by using impact energy. When enter the zone of the board hammer, the raw material is crushed by the high-speed impact of it. And then the raw material is threw up to the impact device installed on the rotor and is crushed again. Then the raw material is crushed for another time when it is rebounded from impact liner to the zone of board hammer. The process repeats until the raw material is crushed into the desired size and discharges from the bottom of the machine. The final product size and shape can be changed by adjusting the gap between impact frame and rotor frame. European Type Impact Crusher adopts spring safety device behind the impact liner. When the non-crushed items enter the crusher chamber, the impact frame front and back will be draw back and the non-crushed items will be discharged from machine.
