Sand Washing Machine
BinQ screw sand washing machine is mainly used for sand processing, electric pole factory, building work site and concrete dam, various sands classifying and dewatering.This sand washer adopts inclination of 15º, 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.
LXS series screw sand washing machine can be used to separate dirt and soil from sand. The new sealing structure, asjustable overflow weir plate, reliable transmission make sure the cleaning and dewatering. It is suited in highway, hydroelectic, building and construction area.
Working Principle of Screw Sand Washing Machine
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.
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.
Features and Application
Spiral sand washing machine is mainly applied to washing minerals of large slit content, such as iron, manganese, limestone, tin ore, etc. It carries out mixing, washing, separating, and desliming. With a washing pressure less than 147-196kpa, it is also suitable for washing building materials in construction and power station applications. The gear transmission parts of our spiral washing machine are separated from stones, water and sands, which greatly reduces the error rate of our spiral washing machine.
Spiral washing machine has features like long spiral structure, good sealing system, simple structure, strong processing capability, convenient maintenance, good washing efficiency, etc. It is widely used in mining industry.
