Fine Sand Recovery Machine
LZ Series
It recovers the fine sand that a washer sends out with its overflow. A conventional washer loses 5–20% of the finished sand to the waste water; a recovery unit concentrates that stream in a cyclone and dewatering screen and puts it back into product, while the returned water runs clearer and the settling pond has less to do.
- Recovers 5–20% of finished sand — usually paying for itself within a year
- Cyclone concentration plus a high-frequency dewatering screen, down to 0.075 mm
- Solids in the return water drop sharply, cutting pond size and dredging

Selection note：Standard LZ figures. Actual recovery depends on overflow density and fines content. Size it against the washer circulating water flow — too small and sand still escapes, too large and the capital is wasted.
