The XL screw sand washing machine is mainly used for sand processing, electric pole factory, building work site and concrete dam, various sands classifying and dewatering.The screw washer adopts inclination of 15°, under the water tub, three weir plates form the sediment pool, the screw head is immersed in this pool, the screw is driven by electric motor through reducer rotating continuously, the fresh water is feeding from porous plate at bottom of sediment pool, this machine have three functions of washing, dewatering, classifying.
Working Principle Of Screw Sand Washing
Washing:The sand is feeding into the sediment pool from the feeding box, acting by rotating screw blade, the sand is turning and rolling and grinding each other to eliminate impurity and water-air layer around sand to facilitate de-water. The fresh eater rising current from the porous plate carry foreign matter to water surface and overflow the weir plate, to finish washing processing
De-watering:The sand with bigger density is sunken down to tub bottom, the screw blade pushes this sand upwards, when passing through upper tub of proper length above water level, the water is draining into sediment pool from another drainage ditch, the de-watered sand is out from the discharging opening.
Classifying:Material classifying is realized by overflowing the non-needed fines, the controlling method is adjusting height of overflowing weir and adjusting speed of screw.
| Model | Spiral Diameter (mm) | Number of Spiral (pcs) | Feeding Size (mm) | Capacity (t/h) | Water Consumption (m3/h) | Motor Power (kw) | Overall Dimensions (mm) | Weight (t) |
| XL-762 | 762 | 1 | 75 | 9-63 | 11 | 9070×2650×1530 | 5.20 |
Driven by electric motor and decelerator, the impeller of sand washing machine moves in a circle in the water groove, thus make the sand or slag pellets mixed, overturned, cleaned and discharged in the water groove.XL series Screw Sand Washing Machine price in Alibaba There is little loss for medium-sized and fine sand and stone powder. Sand Washing Machine The grade and the fineness of the sand for construction after being washed can be up to the national standards, such as sand for construction and cobble and broken stones for construction. There are no other wear parts except the screen mesh. Sand Washing Machine has longer service life and little maintenance chance.
