Abstract
To remote granular or fibrous material from an air stream, the material (1) is passed into an upper opening (2) of a shaft (3) and a vortex of air stream is produced. Air is passed through the upper charge opening of the shaft together with the material (1) and the extra air is drawn into ther swirling flows. Thus, the granular material and additional air are separated from the discharged fine material and exhaust air flow through a perpendicular partition (26), which ends above the axis of the air vortex. The screening boundary w.r.t. the separation of the coarse and fine particles can be adjusted by moving the partition.
