Sand washing plant

Sand washing plant

A sand washing plant is a facility designed to clean sand by removing impurities such as dust, silt, and clay from the surface. It is commonly used in construction, mining, and industrial sectors to produce high-quality sand for various applications.

The process begins with the feeding of raw sand into a hopper or conveyor, where it is transported to a vibrating screen or scrubber. Here, water is added to the sand to create a slurry, which helps in the removal of impurities. The vibrating action or agitation breaks down clumps and separates the sand particles from debris.

Once separated, the sand and water mixture is pumped into a series of hydrocyclones or classifiers, where finer particles are separated from the coarser ones. The fine particles are typically removed as slurry, while the coarse sand is discharged onto a dewatering screen.

On the dewatering screen, excess water is drained, and the clean sand is conveyed for further processing or stockpiled for sale. The water recovered from the process is often recycled back into the system, minimizing water consumption and environmental impact.
