Product Description

Introduction of spiral sand washer:
spiral sand washer is a high-efficiency sand washing equipment adopting wheel-like structure, which works with sand making machine. It can wash the stone powder and impurity from the mixed sand that made by sand making machine, which can improve the sand quality. The Sand Washing Machine is widely used in washing, grading and dehydrating in the industry of stone factories, construction site and quartz sand in glass industry.
 
Features of sand washer:
1. High efficiency, reasonable structure, high capacity and low consumption
2. The bearing device of impeller drive is separated from water and materials in water, which greatly protects the bearing from soaking, sand and pollutants.
3. Compared with the spiral sand washing machine, the loss of medium and fine sand and powder is minimized, and the grade and fineness can meet the required standard
4. This machine is with long service life and low maintenance costs.


Working principle of sand washer:
The electric motor runs slowly with the impellor after decelerated by the belt, decelerator and gears wheel. The sand and stone flow into washing launder from feeding launder, rolls with the impellor, and grinds each other. The impurity covering the sand is washing away. At the same time, add more water, the strong water flow will take away waste and some low-weight wastes from washing launder. On one hand, water is removed from the sand and stone; on the other hand, the water can be fully used. Finally, the sand and stone goes to the out launder from the rotary impellor to finished. Then clean sand and stone is lift up by vane. When it goes up slowly, the water begins to drop through the mesh and fall back in the washing launder. Finally, the sand and stone goes to the out launder from the rotary impellor to finish the washing task.
