Working Principle And Characteristics Of Pneumatic Pavement Breaker

The pneumatic pavement breaker uses high-speed impact to crush materials. When the material enters the action area of the blower from the material inlet, it is crushed for the first time by the high-speed impact of the blower. The strong impact force throws the material onto the counterattack board and breaks again, and the material rebounded by the counterattack board falls to Continue to repeat the above process until the material is crushed to be smaller than the size of the discharge port, and discharged from the discharge port due to its own weight.

1. It has large crushing ratio, simple and reasonable structure, stable operation, simple maintenance, convenient and quick replacement of parts, and high crushing efficiency. It is widely used in industrial sectors such as building materials, mineral processing, chemical industry and electric power. It is mainly used to crush materials with medium hardness and brittleness.

2. After optimized design, the crushing cavity is enlarged and the feed size is increased. Through the optimized liner and specific rotor, the production efficiency under various application conditions is greatly improved.

3. High chromium materials and high manganese steel materials are used for the plate hammer, impact liner on the rotor of the crusher and the vulnerable parts in the cavity, which improves the durability of the vulnerable parts (such as the plate hammer, impact liner, etc.) and the reliability of crusher mechanical parts (such as main shaft, bearing).
