1.The structure of the machine is simple, and the impeller drive bearing device is isolated from water and water-receivin materials,which greatly avoids the damage of the bearing due to water immersion, sand and pollutants.
2. There is very little loss of medium-fine sand and stone powder, and the grade and fineness modulus of the washed building sand meet the standards for building sand,building pebbles, and gravel.
3. The machine has almost no wearing parts except screen.
4. Long service life, no maintenance for a long time.
