  • Patent number: 12138635
    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.

  • Patent number: 11833525
    Abstract: The invention relates to a method for separating feed material, wherein the feed material comprises at least one ferromagnetic material fraction and a non-ferrous material fraction, wherein a conveying stream is fed to a first separation of a first ferromagnetic material fraction, in particular by means of a first magnetic separating device (1), wherein the conveying stream is subsequently fed to a second separation of a second ferromagnetic material fraction from the conveying stream, in particular by means of a second magnetic separating device (2), and wherein a redistribution and/or reallocation of the material of the conveying stream takes place between the first separation and the second separation.
