1.Powerful Mud Removal Effect

Screw stirring creates sufficient friction between sand materials to strip clay and sludge thoroughly, producing high-purity finished sand.

2.Durable & 使用寿命长

Wear-resistant alloy spiral blades and thickened tank body resist abrasion from sand stones, low failure rate and fewer replacement parts.

3.Low Water Consumption & 操作简单

Reasonable water circulation design saves water resources; simple structure, one-person operation, convenient daily maintenance.

4.应用广泛 & Stable Output

Applicable to manufactured sand production lines, quarry, mine, concrete mixing plant; stable operation even under continuous heavy-load working conditions.

工作原理

The spiral sand washing machine is driven by a motor, with the impeller rotating slowly via a V-belt and a reducer. Materials (such as sand, gravel, and ore) enter the washing tank from the feed chute and are tumbled and agitated by the impeller to remove impurities from their surface.

• The material is tumbled and agitated within the washing tank by the impeller.

• During this process, collisions and friction occur between the materials and between the materials and the impeller and casing, which helps remove impurities such as mud and stone powder from the material’s surface.

• Lighter impurities and foreign objects are carried away by the water flow and discharged from the drain outlet of the washing tank.

产品结构

Rotary Spiral Shaft: The rotating shaft is the core component of the coarse aggregate washer. Its inlet end is equipped with blades for scrubbing; the rest of the shaft is conveyed to the outlet by a screw conveyor. Increasing the number of blades on the shaft improves the scrubbing effect; however, increasing the number of blades reduces the throughput.

Washing Tank: The washing tank holds the aggregate to be processed. The rotating shaft is installed inside the tank, where the aggregate is scrubbed and cleaned.

Upflow Classifier: The upflow classifier within the washing tank of the coarse aggregate washer helps optimize machine performance. The upflow helps to remove unwanted lightweight materials such as branches, sticks, and coal lumps with the wastewater.
