Product Introduction

The spiral sand washer is a type of sand washer that mainly stirs the sand and gravel materials through the spiral device in the equipment, gradually screens them under the action of the spiral device, and discharges them from discharge opening at the top , thus achieving the cleaning and screening effect of the sand and gravel materials.

The spiral sand washer is suitable for washing, screening, and removing impurities in industries such as metallurgy, construction materials, and hydropower. It is especially suitable for washing fine-grained and coarse-grained materials, and is ideal for building sand and road sand. The spiral sand washer has the advantages of low power consumption and high cleanliness. Its good sealing structure, fully enclosed transmission device, and adjustable weir plate ensure the durability, good cleaning and dewatering effects, and stable retention of fine-grained products.

Applicable Materials
Mechanic sand
River pebbles
Natural sand
River sand
Quartz sand
Product Performance
Large processing capacity: The washing principle of the spiral sand washer does not rely on a bucket to scoop the sand, resulting in a greatly improved processing capacity.
Higher energy utilization: It reduces the energy consumption loss caused by the bucket during the lifting process, enabling better utilization of energy.
Minimize the wear of some components: The spiral sand washer does not require the addition of a screen, reducing the loss of the screen and extending the service life of the equipment.
Better cleaning effect: Compared with the bucket-type sand washer, the spiral sand washer flips and cleans the sand more times, resulting in a better cleaning effect.
Separation of bearings, water, and materials: It avoids the damage caused by early rusting of the machine due to pollution.
Operation Principle

The spiral sand washer consists of a tank, reducer, motor, central shaft, spiral blades, and bracket. The machine rotor adopts a central structure, and the spiral blades are installed on the central shaft, which is connected to the reducer for operation. It is a kind of mechanical separation equipment based on the principle that solid particles settle at different speeds in a liquid due to their different specific gravity.

The spiral sand washer has a reasonable structure, convenient maintenance, large processing capacity, low power consumption, and high cleanliness. Its novel sealing structure, fully enclosed oil-immersed transmission device, and adjustable overflow weir plate ensure the durability, good cleaning and dewatering effects, and stable retention of fine-grained products.
