  • Working Principle of gold mining impact crusher:

    Impact crusher is a kind of crushing equipment which uses impact energy to crush maters. When getting into the effective area of hammer plates, due to the high speed of striking, the raw materials are thrown onto the impact equipment which is installed above the rotor. Then the materials are rebounded to the effective area of hammer plates and crushed again in the crushing chamber. At last, when the particles reach to the proper size, they will be discharged from the bottom of the machine.

     

    Operation Principle of gold mining impact crusher:

    The impact crusher 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 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.

     

    Structure of gold mining impact crusher:

    The impact crusher 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 12°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 12 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.
