General introduction to spiral classifier

Spiral classifier, as one of the important machines for ore separating, consists of transmission, spiral, groove, elevator, bearing bush and ore discharging valve. According to the principle that solid particles have different weights and speeds to precipitate in liquid, spiral classifier is produced and used for mechanical classifying.

Working site of Fote spiral classifier

Spiral classifier, also called classifier or screw classifier, has four kinds: high-weir single-spiral classifier, high-weir double-spiral classifier, submerged single-spiral classifier and submerged double-spiral classifier.

Spiral sand washer

As a kind of sand washer, screw washing machine can clean and screen sand materials. Spirals inside can agitate the sand materials and make mud mix with water. The mix flows out from upper part. While, the sand materials are gradually screened by spiral device and discharged out from mouth.

Spiral sand washer is suitable for washing, classifying and dedusting materials in industries of metallurgy, building material and hydropower, especially for building sand and road gravels. The spiral sand washer enjoys features of good sealing performance, enclosed transmission, adjustable weir plate, high working efficiency, good dehydrating and long service life, etc.
