Abstract
The separation of materials according to their density is carried out in a fluid bath by floating ground light materials and carrying same over an overflow, as well as depositing ground heavier materials on a horizontal sieve base within the fluid bath. In order to improve the floating of the lighter materials, a displacement body is cyclically sunk into the fluid bath. The fluid bath is supplied with additional fluid in a synchronous manner with the cyclical movement of the displacement body. A control device for supplying the fluid can also be connected to pressure sensors or the drive of the displacement body.
Claims7
A method for separating mixtures of ground materials according to their density in a fluid bath with at least one sieve floor, on which heavier parts of the inserted mixtures sit, and a device to create a cyclical change of pressure in the fluid bath,
- so characterized in that
- during an increase in pressure a predetermined amount of additional fluid is inserted into the fluid bath.
A device for separating mixtures of ground materials according to their density in a fluid bath with at least one sieve floor, on which heavier parts of the inserted mixture sit and with a displacement body, which is dipped cyclically into the fluid bath,
- so characterized in that
- a control device is provided, which during dipping of the displacement body introduces a predetermined amount of additional fluid into the fluid bath via a supply pipe.
