  • Three Factors Affect the Classifying Effect of Spiral

    2019-9-23 · The spiral classifier is one of the important mineral processing equipment whose working principle is to classify the materials by using the difference in the settling speed of solid particles in the liquid. The classifying effect of the spiral classifier will directly affect the content of the qualified product in the returned sand thus affecting the grinding efficiency of the grinding mill.

    Spiral Operation. Slurry enters the spiral through a feed box and is introduced on to the spiral surface. Once on the spiral surface the mineral grains settle and sort according to size shape and specific gravity. Generally the particles with the lowest specific gravity are carried with the water towards the outside wall of the spiral.
