Counterattack crushing machine work principle: In the main frame, a 100-1500 kg powered pressure spring is fixed to the roller suspender. After the counterattack crushing mahine is put into effect, the roller rotates around the main shaft, and rolls closely against the ring effected by the high pressure spring and centrifugal force. And its rolling pressure is 1.2 times higher than that of the Raymond counterattack crushing mahine under the same power condintion and the output is raised to substantial degree. When the stuff is loaded into the counterattack crushing plant cavity, it is shoveled into the space between the roller and the ring for crushing. The resulted powder is routed to the seperator along the circulation wind of the blower and the standard fine powder is guided to the cyclone collector as final product and large size stuff falls back to the counterattack crushing mahine for regrinding. The circulation wind returns to the blower to repeat the above process and the remainder wind enters into bag deduster for purification. When a certain degree of wear of roller and ring is caused, it is recommended to adjust the length of the spring to maintain the constant pressure between the roller and the ring. As a result, the stable output and fineness are ensured. Impact Crusher Operating principle: It is a kind of crushing equipment, using impact energy to crush materials. When materials get into the area where the board hammer plays a part, under the impact function of board hammer at a high speed, the crushed ones are thrown to the impact device above the rotor continuously. And then they are rebounded from the impact liner to the area where the board hammer plays a part, and are impacted again. The materials from large ones to small ones get into the impact cavity for being crushed repeatedly. The process is going on until the materials are crushed to the required sizes and discharged from down of the machine.
