Common correct media sump and wing tank design

Abstract

In a coal preparation plant which receives a raw coal feed and separates the raw coal into clean coal and refuse, an apparatus is provided for use therein. The inventive apparatus is a combined sump common to the heavy media vessel and heavy media cyclone circuits used for recirculating medium storage for the heavy media vessel circuit and mixing device, referred to as a wing tank, to proportionally combine intermediate sized raw coal feed particles with a slurry of media and water for feeding the heavy media cyclone circuit. The advantage of this combined system is the ability to use a common recirculating media for use in both the heavy media vessel and heavy media cyclone circuits, without sacrificing the ability to have different recirculating gravities for each separating circuit.
