ABSTRACT:
In classifying apparatus of the type wherein upward whirling flow of fluid is used to separate coarse and fine particles of the particulate material, rotary vanes are mounted on the upper portion of a housing for separating and discharging fine particles, and a rotary disc carrying a plurality of nozzles is provided for projecting jet streams of the fluid against the inner wall of the housing. Vertical and inclined guide plates are provided near the inlet port of the fluid for smoothly guiding coarse particles falling down along the inner side of the housing without being disturbed by the whirling flow of the fluid admitted through the inlet port.
