A handling material is put into the pulverizer by table feeder.
Air that is absorbed through the inhaling pressure of SUCTION FANDML
and a handling material are mixed and grinded between the pin and the liner in the grinding chamber.
The grinded powder, along evenly distributed ascending currents, is moved to the air classifier part.
At this time, by the rotating speed of the air classifier, the centripetal force and the centrifugal force are created
Powder, influenced by the centripetal force, is absorbed up into the discharge nozzle (6),
together with air, and thick particles, influenced by the centrifugal force, can't pass through the classifier
so they go back to the grinding zone (8) to be grinded again. In order to make the particle size smaller,
rotational frequency of the air classifier should be increased. At this time, in order to prevent the phenomenon of
bottle-neck in the pulverizer, the speed of feeding a handling material into the pulverizer should be lowered
