1. Introduction of Screw Sand Washer
The XL series screw sand washer is used for removing the dust and impurities mixed in the sand,applied to washing, grading and dehydration for sand. It aims at improving the quality of sand.developed on the basis of introducing foreign outstanding technology of the same kind of products.It is widely used for cleaning materials in the following industries: highway, water conservancy and quarry, minerals, construction, chemical industry, and hydropower, cement mixture station and so on.
are widely used in the distribution of ore in closed circuits with ball mills, grading ore and fine slit in gravity mills, grading granularity and flow of metal ore-dressing, and de-sliming and dehydrating in washing.
This screw sand washer can filter materials and send coarse materials to the feeding mouth and discharge fine materials from the pipe. The seat of the machine features channel steel material, while the body is armor plated and the spiral axle is made of cast iron for durability. The machines lifting equipment can be used manually or electronically
2.Type of Screw Sand Washer
According to the spiral blade at the flooding end, there are two type screw sand washer:
1.the top side of spiral blade is higher than the flooding level and the center of the blade is lower than the flooding level. This type is used for classification of ore with flooding size between 0.83-0.15.
2. the whole spiral blade is immersed in the flooding level of the flooding end. The type is used for classification of ore with flooding size between 0.15-0.07mm.
3.Working Principle of Screw Sand Washer
When the screw sand washer works, the motor drives the impeller to rotate slowly. While the dirt and impurities are removed by the added water, the large blocks are conveyed by the rotating impeller to the discharge chute.
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 push 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.
4.Features of Screw Sand Washer
XL series screw sand washer has the characteristics of reasonable structure, convenient maintenance, high output, low power consumption, and high degree of cleanness. Its novel sealed structure, totally-enclosed oil-bath transmission system, and adjustable overflow slice ensure the characteristics of high efficiency, durability, cleanness, and good dehydrating effect, and reliable product size.
5.Technical Parameter of Screw Sand Washer :
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.2018 Yuhong Screw Sand Washer/ Sprial Sand Washing Machine Price/Sand Washing Plant 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.
