Description
Feed slurry is introduced into the bowl through the centre of the conveyor where the solids settle through the liquor pool formed in the bowl. The gearbox produces a slight differential speed between the rotation of the bowl and that of the screw conveyor which conveys the solids along the bowl wall, out of the liquor pool, and up the conical section of the bowl to the solids discharge ports. The clarified liquor (centrate) discharges continuously from the opposite end of the bowl over adjustable weir ports.
