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.
