Chamber of small ore concentrate for a jig

摘要

A centrifugal jig has a container mounted for rotation about its longitudinal axis. The container is separated into an axial region and a peripheral region by ragging material supported by a screen. The peripheral region is composed of a series of hutch chambers with reciprocating wall portions located radially outside the screen, for repetitively dilating the ragging. The disclosed hutch chamber construction has a reciprocating wall portion which includes convergent wall surfaces that narrow toward the hutch chamber concentrate outlet.
