Which sand washing machine is best suited for processed manufactured sand

Sand washing machines remove impurities from sand, serving as auxiliary processing equipment in aggregate production lines. After washing, manufactured sand exhibits significantly improved cleanliness and superior quality. Given the relatively straightforward production process of sand washing machines, numerous manufacturers exist in the market. Which manufacturer stands out? We recommend OCP Heavy Industry.

Generally, sand washers fall into two categories: bucket wheel sand washers and spiral sand washers. These two types operate on different principles and thus suit different applications. Below is a detailed description of the performance differences between them:

1. Bucket Wheel Sand Washer

Driven by a wheel-shaped structure, this machine continuously rolls and washes sand within the washing trough. The sand particles grind against each other to remove impurities covering their surfaces. It also disrupts the surface vapour layer of the material, promoting dehydration. As water is continuously added to the wheel, it forms a powerful current that carries away lighter impurities and contaminants. The cleaned sand is discharged from the overflow outlet of the washing trough, completing the entire cleaning process.

The bucket wheel sand washer features a simple structure, with water and sand isolated from the main drive mechanism to prevent contamination and bearing wear. The screen mesh is removable, allowing sand particle size classification to be adjusted according to user requirements, facilitating replacement and maintenance.

2. Spiral Sand Washer

The spiral sand washer utilises the buoyancy of water and the principle that solid particles settle at different rates in liquid due to variations in specific gravity for classification. The machine's rotor adopts a central structure, with spiral blades mounted on a central shaft driven by a reducer. The spiral sand washer requires inclined installation, with the lower section of the water trough enclosed by three-sided weir plates to form a sedimentation tank. The spiral head is submerged within this tank, driven by an electric motor via the reducer for continuous rotation. Cleaning water is supplied through a perforated plate at the sedimentation tank's base. This equipment combines washing, dewatering, and classification functions.

Commonly employed in mineral processing lines, this sand washer achieves high cleaning efficiency with low power consumption. Adjustable weir plates, coupled with a fully sealed transmission system, ensure efficient and stable operation, particularly for fine sand materials.

Within contemporary sand and gravel production, the sand washer has become indispensable equipment, enhancing sand purity and marketability. OCP Heavy Industry's sand washers not only deliver superior cleaning results but are also competitively priced. Sold at factory-direct rates without intermediary mark-ups, they offer users greater profit margins.
