Granule stream divider for a countercurrent air classifier used for cleaning dust from plastic granules

摘要

A box elbow (1) effects controlled centrifugal separation of a gas-entrained granule stream (13) into sub-streams (14,15,16). A granule stream divider consists of a box elbow (1) which effects controlled centrifugal separation of a gas-entrained stream (13) into two or more sub-streams (14,15,16) upstream of a countercurrent classifier.
