Advantages and Disadvantages of Spiral Sand Washers

Spiral Sand Washers Advantages

1. Spiral sand washer can be installed in inclined horizontal layout. Materials get more frequent overturning and longer cleaning time for superior washing effect.

2. Bearings are isolated from water and materials, effectively preventing early rusting and equipment damage caused by contamination.

3. Cast iron sleeves are fitted at water inlet and shaft ends of the spiral shaft, ensuring stable and flexible operation.

4. Stone powder content is easy to control, adjustable from 2% to 15% within the particle range of 0.00-0.75mm.

5. Liner plates are adopted to lower maintenance frequency. The base is made of channel steel and the main body is welded with steel plates, featuring solid structure and excellent wear resistance.

Spiral Sand Washers Disadvantages

1. Spiral sand washer is more expensive than wheel sand washer, hence not recommended for clients with limited investment budget.

2. Spiral sand washer occupies larger floor space, with overall length ranging from 8m, 9m up to 11m.

3. During operation, the spiral sand washing machine is tilted with one end lower. Bearings at the lower end are immersed in water; insufficient sealing easily leads to bearing damage and troublesome part replacement.

4. It causes relatively high sand loss rate.
