WIMA Density Separator


Our HDS-S presents the compact entry-level solution for water-based density separation.

Operation Principle:

The machine comprises a separation chamber, a discharge conveyor for lightweight materials, and a screw conveyor for heavy materials. The core element is the continuously adjustable propeller in the separation chamber. This propeller allows for the adjustment of flow velocity for various materials. The continuously adjustable propeller generates an upflow in the separation chamber, transporting lightweight materials onto the discharge conveyor. Heavy materials sink to the bottom of the separation chamber and are discharged using the screw conveyor. This screw conveyor is soulless, enabling the conveyance of heavy materials with an edge length of up to 150 mm.
By adjusting the flow velocity, materials with a density greater than 1g/cm³ can be transferred to the lightweight fraction.
