Mining Machinery

Materials enter into the crusher through hopper and divided into two parts materials by the feeder. The middle part of the sub-feeder into the high-speed rotation of the impeller, the impeller was in rapid acceleration, its acceleration can be several hundred times the acceleration due to gravity, and then to 60-70 m/s from the impeller speed of the three uniform flow within projectile out, first of all by the sub-feeder with four weeks since the close down part of the material impact crusher, and then with the impact of the vortex support material lining the cavity, the lining material rebound angle on the impact of the eddy at the top of cavity and change the direction of its movement, bending down movement, rotation from the leaf material fired out of a continuous material curtain. This material has been a whirl cavity broken several times by two probability and impact, the role of friction and grinding broken. Broken material discharged from the lower level discharge opening. And recycling the formation of closed-circuit screening system, three general circulation materials can be broken into the following 20 heads. Under the broken in the whole process, the material impact of each on its own broken, do not have direct contact with the metal components, but the occurrence and impact of lining materials, friction and grinding, which reduces the pollution, the extension of time to mechanical wear. Eddy currents clever internal cavity from the circulation, the elimination of the dust pollution.
