These series of impact crusher are designed for crushing ores and rocks with particle sizes less than 100-500mm and compression strength no more than 320MPa.It has features of big crushing ratio, high-efficiency crushing, cubic shape, selectable crushing, etc. It is widely used in highway, hydropower construction, airport and building industries
Working Principle of Impact Crusher
The 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 repeats 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-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.
