Centrifugal separator is intended for getting kaolin, talc, chalk stone and other soft materials coming from dryers and mills. Separator consists of the following main assembly units: head, classification chamber, hopper, shaft, rotor, reflector, shock absorber, support, cover, lubrication system, branch pipe.
When supplying dust air mixture to separator underneath through hopper air duct, the dust air mixture twirls by the blades and is lifted upwards to the rotor. In this zone from the rotor blades, the air counter-flow begins from the rotor blades that create braking action on larger particles, they are whether rejected to the classification chamber wall or descending under action of gravity force.
Small particles go between the rotor blades and enter the head air channel through the head sidewall holes; the head air channel has a spiral form; then they enter the settle out cyclones through the branch pipe on air. Then the cleaned air from small material on air ducts by fan goes to separator. One air flow through the branch pipe goes for additional blasting of large material settling from the classification chamber, other air duct grasps the material for separation from the mill. This system has a closed type with minimum discharge of air excess into the filters for dust collection.
When loading material from above the separator, the material enters the dispersive rotor disc and under action of centrifugal forces is scattered from it in thin layer. Larger particles reach the classification chamber walls and are settled underneath on it. Smaller ones are ascending by air flow upwards from dispersive zone and reach the rotor blades. Further the separation process goes the same way as described above.
The separation principle is the same when supplying the material for separation simultaneously from above and from below.
Separator operation processing mode for getting a specific material (rotor speed, air quantity required for large material blasting and material supply into the separator) for each material is chosen individually.
