Abstract

A counterflow separator is provided having a feed pipe for bulk material opening into the top of a chamber housing. A discharge conduit radial extends from the top of the housing and an inlet conduit for classifying air extends radially into the housing at its lower portion. The housing is provided with a wall section below the orifice of the feed pipe, which section expands conically outwardly into a collecting hopper. The conical wall section permits the design of a braking stretch longer than its own length, thus reducing the requirement for classifying air, without causing a deterioration in the classifying quality.
