Screw Sand Washing
Zenith 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 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, dewatering, 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.
