Sand washing machine is really a sort of cleansing equipment of international sophisticated level for sand and slag pellets, it really is formulated within the basis of introducing foreign excellent engineering of the exact type of products.
Sand Washing Machine Structure
Sand washing machine adopts inclination of 15,under the water tub, three weir plates form the sediment pool, the screw head is immersed within this pool, the screw is driven by electric motor via reducer rotating continuously, the fresh water is feeding from porous plate at bottom of sediment pool, this machine have 3 functions of washing, dewatering, classifying.
Working principle of 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.
Sand washing machine operating principle
Sand washing machine operating principle is as following. Sand washing machinery drives the impeller in the water groove to move like a circle transmitted by electric motor and decelerator, and then mixes, overturns, cleans and discharges the sand or slag pellets in the water groove.
