Desander LSSF

Our LSSF series Spiral Desander is used for the removal of sands in the mixture of liquid-solids. It consists of shaftless spiral, liner, U-shaped groove, water tank, deflector, weir and driving device. Working principle: The mixture of sand-liquid is pumped into water tank at the lower side. The sands would be deposited at the bottom of groove. Driven by spiral , the sands are pushed up along the inclined bottom of groove. When above water level, the sands continue to move up for a distance till water completely removed, then to be discharged into the sand barrel. The separated liquid if it contains organic substances can be delivered into anaerobic reactor for biogas generation.
