A sand washing machine, also known as a sand washer, removes dust, clay and organics from natural sand or crushed rock fines, producing cleaner, drier aggregate that meets concrete, asphalt and masonry specifications.
Our integrated sand washing machine combines a wheel washer and a fines recovery unit in one all-in-one skid. It washes, dewaters and recycles fine sand in a single pass — that is why we also call it a sand washing and recycling machine.
The LZZG unit separates ultra-fine particles below 150 microns from manufactured and natural sand, and discharges finished material at about 12% moisture. The real advantage is low sand loss: the hydrocyclone recovers more than 90% of the 0.074–3 mm fraction that a typical wheel or screw washer would otherwise send to waste.
It is the core equipment of a complete sand washing plant, and is widely used for washing, dewatering and classifying crushed sand, gravel, river sand and sea sand in quarries and concrete operations.
Washing: Feed material enters the washing tank through the feeding chute. The rotating impeller lifts and rolls the aggregate, creating inter-particle attrition that strips clay and dust from the sand surface, while a continuous water flow carries the loosened fines and sludge out through the overflow.
Recycling: The overflow water, carrying 0.074–3 mm fines, is pumped to a hydrocyclone. The cyclone spins the slurry at high centrifugal force, dropping the sand fraction down through the apex while the dirty water overflows back to the settling tank.
Dewatering: Coarse sand (3–10 mm) from the washing tank and the recovered fine sand (0.074–3 mm) from the cyclone both report to the dewatering screen. After dewatering on polyurethane panels, the finished material leaves at 8–12% moisture — ready to stockpile, convey or truck.
