70-110​ t/h Screw Sand Washer Machine for Sand Washing De-watering Classifying

Brief Introduction of Spiral Sand Washing Machine

Spiral sand washing machine is mainly used for many sandstone industries such as: sandstone factory, building work site, hydroelectricity dam, glass manufacture, oil well development. The machine is specially designed for sandstone and quartz sand company to wash, separate, and classify and dehydrate.

Working Principle of Spiral Sand Washing Machine

This sand washer should be installed with an angle of 15 degree, 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.

Washing:

The sand is feeding into the sediment pool from the feeding box, with the help of rotating screw blade, the sand is turning, rolling and grinding each other to eliminate impurity and water-air layer around sand to facilitate de-water. The fresh water rising current from the porous plate carries 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 fine particle that does not meet the standard requirements. The controlling method is adjusting height of overflowing weir and adjusting speed of screw.

Technical parameters:

Note: No further notice if the technical parameters change.
