Spiral classifier plant is widely used to form a closed cycle process to separate mineral sand with ball mill in ore dressing plants, grade ore and fine mud in the gravity ore beneficiation plant, or for the ore pulp size classification in the mineral beneficiation process, as well as desliming and dehydration in washing operations. Spiral classifier has the characteristics of simple structure, reliable work, and convenient operation, etc.
Spiral classifiers are typically mechanically-driven devices, which drags coarse sandy sediment materials from the settled feed pulp by a continuously revolving spiral setting along the bottom of an inclined surface to a higher discharge point at one end of the settling tank.
As the ore pulp follows the spiral channel the light particles in the pulp stream move outward and upward into the fast-flowing portion of the stream while the heavy ore particles move to the inner slow-moving portion of the stream, where they are drawn off through concentrate ports.
