Pulsating Hutch chamber for jig

摘要

A centrifugal jig has a container mounted for rotation about its longitudinal axis, 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. A hutch chamber is disclosed having a construction applicable to both rotary and non-rotary jigs, having a reciprocating wall portion, which includes a pulsating diaphragm leading to the hutch chamber concentrate outlet.
