Abstract
Abstract A centrifuge bowl head including a bowl head plate, a bowl spoke attached to an outer circumference of the bowl plate, and a bowl spoke plow attached to the bowl spoke, the bowl spoke plow impinging upon a wearing material at an angle less than seventy-five degrees. A bowl head further including a bowl head plow connected to the bowl head plate, the bowl spoke plow having an additional directing angle, the bowl spoke plow being of unitary construction and the bowl spokes defining discharge ports, the area of the bowl spokes forming a ratio with the area of the discharge ports to allow material under the bowl spokes to have an included angle of 120 degrees or less.
