The settled material is transported via by a shaftless screw conveyor from the separator, as wet solids and the effluent is returned into the process.

The screw is only supported by a bearing at the drive-end. The advantage of this is that the larger particles cannot jam between the screw and trough.

The sand screw separators are available in a range of sizes from 35m3/hr to a maximum capacity of 125 m3/hr, dependent on type and the settling velocity of the material to be removed.
