The work style of this series sand washer is rotary and movable. The bucket is driven by motor through reducer and rotates in circle. There are many sand storage web grooves in grille form. When the bucket moves, sand can be put out by storage web groove after being cleaned, waste water outflows through web groove’s holes. Meanwhile the washed sand will be fed into PU screen directly for dewatering. In the process of sand washer is running, sand is discharged through the feeding groove. Sand washer can circumrotate and discharge sand periodically by motor’s continuously running, which can realize the batch production. It works the same as XSD sand washing machine. After vibrating and dehydrating on the PU screen, dry sand is the final product.
