Blender system with concentrator

Abstract

A blender system includes a blender tub for blending a solid particulate material in a liquid. The tub has a tub outlet defined therein. The system also includes a pump having a pump suction inlet and a pump discharge. A suction conduit is provided for conducting a tub outlet stream from the tub outlet and a liquid supply stream from a liquid supply to the pump suction inlet. A solids concentrator device is provided for separating a pump discharge stream from the pump discharge into a lower density recirculating stream and a higher density concentrator discharge stream. The concentrator device has a concentrator inlet for receiving the pump discharge stream, a low density outlet for directing the recirculating stream back to the tub, and a high density outlet for discharging the concentrator discharge stream.
