Adopting the latest manufacturing technology and unique structure design, the PF series impact rock crusher can produce cubic products with very good grain shape without tension and crack. It can crush each kind of coarse, medium, fine cubic material (granite, limestone and concrete etc) with feeding size not more than **0mm and crushing strength not more than **0MPa and is widely applied to secondary and tertiary crushing of various ores and medium- hard materials in railway, highway, energy, cement, chemical industry construction etc.

Structure of Impact Crusher:

The Mineral Impact crusher Machine is mainly made up of rotor rack, impact rack, ratchet wheel cover-open device, rotating parts as well as other components. There are two parallel rotors in the mobile impact crusher, with some altitude differences. The position of the first rotor is relatively high, with an angle of *2°from the ligature of the first and the second rotor. The first rotor is a heavy type, used for coarse crushing; the second rotor rotates fast, which can meet the need of the final product. The rotors are both fixed with bolts. The *2 blow bars distributed to 6 rows are made of high manganese steel. The rotors are fixed on the main shaft, separately connected with the coupling of two engines. All impact boards are made of high manganese steel.

Working principle of impact crusher

When the impact crushing machine works, the motor drives the rotor rotate of the impact crusher with high speed, on the rotor where installed the hammers. When the materials get into the area which the hammers affect, under the impact function of the hammer at a high speed, the materials are thrown to the impact device above the rotor continuously. And then the materials are rebounded from the impact liner to the area where the hammers effects for being recrushed. The materials from large to small all to be crushed at the impact chamber repeatedly. The process won’t stop till the material are crushed to the required size and then discharged from outlet of the impact stone crusher and mineral impact crusher.
