This series of sand washing machine is a wheel-type sand washing machine, which can clean the stone powder and soil in the separated sand. Its novel sealing structure and reliable transmission device ensure the cleaning and dehydration effect. The high-efficiency sand washing equipment used is suitable for washing fine-grained and coarse-grained materials, and is particularly suitable for construction sand and road construction sand.

1. Reasonable structure, impeller drive bearing device is isolated from water and water-receiving materials, which greatly avoids bearing damage caused by water immersion, sand and pollutants;  

2. The loss of medium fine sand and stone powder is very little;  

3. The machine has almost no wearing parts except the screen;  

4. Large processing capacity and small power consumption;  

5. Long service life, convenient maintenance;  

6. Save water resources;  

7. No pollution, high cleanliness.  

When working, the motor reduces the speed of the impeller through the V-belt, reducer, and gear, and the impeller slowly rotates. The sand and stone feed trough enters the washing tank. The impeller drives the roller to roll and grind each other to remove impurities covering the surface of the sand stone. The water vapor layer covering the sand particles is destroyed to facilitate dehydration; at the same time, water is added to form a strong water flow, and impurities and small foreign bodies with small specific gravity are promptly taken away and discharged from the overflow port washing tank to complete the cleaning function. The clean gravel is taken away by the blades, and finally the gravel is poured from the rotating impeller into the discharge trough to complete the cleaning of the gravel.
