Spiral Sand Washer


Spiral sand washing machine is a kind of sand washing machine, which is used for washing, grading, cleaning in metallurgy, building materials, hydropower and other industries. It especially fits in construction sand and road sand.

Working principle

It is mainly used to stir the sand and gravel through the screw device so that the soil and water in the sand and gravel are mixed and discharged from the flow outlet of the equipment. The sand and gravel are gradually screened under the action of the screw device and discharged from the top outlet, thus realizing the cleaning and screening effect of sand and gravel.
The rotor of the machine adopts the central structure, the spiral blade is installed on the central shaft, and the reducer is connected to the central shaft for work. The mechanical extension is carried out by means of the different settling velocity of solid particles in the liquid.

Performance features

1. The sealing structure of the screw sand washer, fully sealing oil bath type transmission device and adjustable overflow weir plate ensure the product’s durability and good cleaning and dehydration effect.
2. Higher energy utilization rate reduces the energy loss caused by the wheel bucket in the process of lifting so that the energy can be better utilized effectively.
3. Reduce the wear of some parts, do not need to increase the screen, so reduce the loss of screen, prolong the service life of the equipment.
4. Better cleaning effect. Compared with the wheel and bucket type, the spiral sand washer takes more time to clean the sand over and has a better cleaning effect.
