ABSTRACT:
Mixed scrap metal pieces 6 are sorted in a fluidised hindered settler containing sand, through which the pieces settle at a differential rate. The sand is fluidised by air from 20 and vibration-driven around a circular trough 2. A depthwise partition 14a sorts the pieces according to settling rate, whereafter they are removed up separate ramps 14 and 16. The sand is levelled preparatory to receiving the pieces 6, and only afterwards is it fluidised.
