Sand washing machine can wash stone powder and residual away from the mixed sands produced by sand producing machine, which can boost the sand high quality mainly. XSD series sand washing machine becomes an important equipment in sand producing production line.
It is widely used for cleaning materials in the following industries: quarry, minerals, building materials, transportation, chemical industry, water conservancy and hydropower, cement mixture station and so on.
Sand washing machine work, motor through the triangle, reducer, gear reducer drive slowly rotating impeller after sand has a feeding trough into the basin, under the drive of the impeller, and mutual grinding, remove cover impurity on the surface of the sand and gravel, and destruction of the coated sand moisture layer, favors the dehydration;Add water at the same time, form a strong current, to take away impurities and the proportion of small foreign body in time, and from the spillway trough eduction, complete the cleaning effect.Clean sand by the leaves away, and finally into the sand from rotating impeller discharge chute, complete sand cleaning effect.
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.
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
Material classifying is realized by overflowing the non-needed fines, the controlling method is adjusting height of overflowing weir and adjusting speed of screw.
