For good dewatering, you always need a pressure filter after thickening. The Dorr traction thickener is the type most frequently used for heavy- duty work with large tonnages. The machine is so called because the thickening mechanism is driven by means of a traction wheel which travels around the periphery of the tank on a rail.
