 Application of PF impact crusher

DongMeng PF series impact crusher is designed for crushing ores and rocks with particle sizes less than 120-300mm and compression strength no more than 350Mpa.

Working principle of PF impact crusher

The impact crusher 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 discharge 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 the machine by the impact rack in the front and back of the machine.

   PF series impact crusher are designed for crushing ores and rocks with partical size less than 120-300mm and compression strength no more than 350Mpa. It has a feature of big crushing ratio, high-effeciency crushing, cubic shape, selectable crushing and etc. It is suitable for crushing different compression strength of rocks and is widely used in mining, cement and concrete industries.
