Good Quality Stone Crushing Machine, PF Impact Crusher

Stone crusher description:
With the communication and cooperation among international mechanical technologies ,advanced German machine and our domestic creation and invention, Dingbo Jaw crusher has been improved greatly in its perfect quality service and high efficient energy-consumption reduction. PF series impact stone crusher is our latest generation of impact crusher, absorbing domestic and international advanced technology of stone crushing, combining the specific industrial conditions of domestic stones industry. Dingbo impact crusher adopts the latest manufacturing technology, the special structural design, processing cubic shaped end products. This crushing machine is used for primary, secondary, fine crushing mining and rocks (for example, granite, limestone, concrete, etc) materials with feeding size less than 500mm and compressive strength less than 320MPa. It is widely used in crushing ores, railways, highways, energy, cement, chemical, building materials and other industries. The output size can be adjusted and the crushing rotor size is variable.


Working Principle
Impact crusher crushing materials 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.
