Impactors. Impactors have blow bars fitted on a rotor along its width. They push material on impact breaker plates and in a series of impacts between plates and blow bars stone is crushed to desired size. Impactors are preferred when the grinding mills are vertical mills or when a roller press is used as pre grinder with ball mill.


Working Principle. The electric motor drives the rotor and the rotor moves, making the hammer rotate in high speed. The materials are crushed in the crusher by the rotated hammer. The end products come out via the strips of the screen under the machine. The size of the granularity can be adjusted by changing the gap among the screen strips.
