1. The structure of the sand washer is simple, and the impeller drive bearing device is isolated from water and materials, which greatly avoids the damage of water, sand and pollutants to the bearing.

2. Compared with the traditional sand washer, the sand washer (stone washer) has the following obvious advantages:

①The loss of fine sand and stone powder is small, and the grade and fineness modulus of washed construction sand reach the standard.

②The sand washing machine is not easy to be damaged and has strong robustness. Except for the screen, there are almost no vulnerable parts.

③It has a long service life. If it is used for a long time, there will be no failure and no maintenance.

3. It has reasonable structure, convenient mechanical maintenance, large work handling capacity, low power consumption, high material cleanliness, and novel sealing structure, adjustable overflow weir plate, and fully sealed oil bath transmission device, which ensure the durability of this series of products, good cleaning effect, dehydration effect, etc.

4. It is mainly used in construction sites, hydropower stations, gravel plants, glass plants and other units, and the work content is to wash, classify and dehydrate smaller grains of sand and gravel.
