Product Description

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.

Spiral Classifier-Product improvement
An automatic elevating apparatus is added to the discharge opening. The scoop in ball mill is eliminated
bringing more stable operation.

Spiral Classifier-Product Application
The overflow spiral blade is higher than overflow level, and the overflow spiral center is lower than overflow
surface. The high wire spiral classifier is applied in the classification of ore with particle size 0.83-0.15mm

Spiral Classifier-Working Principle
The grinded pulp is fed into tank from the inlet in the middle of settlement region, and the slurry classification
sedimentation area is under the inclined tank. The spiral with low speed rotation stirs the slurry, so that the fine
particles rise, and the coarse particles sinks to the bottom of tank. Overflow weir is above the bearing center
which is under screw shaft, and is underneath overflow end.

Spiral Classifier-Product Structure
High weir spiral classifier as the ancillary equipment of grinding to pre-classifying and check classifying is also
applied in de-mudding and dewatering.
