Continuous granulator.

摘要

A continuous granulator includes a granulator body (1) for continuously processing powdered materials into granules, and a screw conveyor (12, 13, 19) for discharging the produced granules from the granulator body (1), the screw conveyor including a pneumatic classifier (10, 14) for separating or classifying the produced granules while they are being conveyed. The pneumatic classifier includes a porous lower portion (14) of the screw conveyor which permits passage of streams of pressurized air therethough into the interior of the screw conveyor. With this construction, discharging conveyance of the produced granules and classification of the produced granules can be carried out concurrently at the same station and hence the granules of a uniform grain size can be produced at an increased rate.
