| Screw Sand Washing |
This product
is mainly used for sand factory, electric pole factory, work-site
of building and concrete dam to wash, classifying and de-watering
various sands.
 
This sand washer adopt inclination of 15°, 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, de-watering, classifying.
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.
