Abstract

A hydraulic density separation device for separating a heavy material fraction with components of higher density from a light material fraction with components of lower density from a feed material includes a conveying device for conveying away the heavy material fraction, receiving chamber which can be filled with water for receiving the feed, a flow generator for generating a water flow in the receiving chamber and a water-fillable separation chamber for receiving the light material fraction. The conveying device has a shaft with a screw conveyor section for conveying the heavy material fraction out of the receiving chamber. The flow generator is designed and arranged such that a flow path of the water flow leads from the receiving chamber into the separation chamber. The conveying device has, in addition to the screw conveyor section, at least one washing section having a plurality of separate paddles arranged on the shaft.
