Spiral Classifier for Mineral Processing

2015-8-6 · Spiral Classifier for Mineral Processing. In Mineral Processing, the SPIRAL Classifier on the other hand is rotated through the ore. It doesn''t lift out of the slurry but is revolved through it. The direction of rotation causes the slurry to be pulled up the inclined bed of the classifier in much the same manner as the rakes do.Spiral (Concentrators) - an overview | ScienceDirect TopicsFor processing of sand minerals normally spirals are being used at onshore where the bottom or base of the plant remain stable and, the heavy minerals (grains with specific gravity generally greater than about 2.9) migrate to the inside of the spiral while the lighter materials (shell, quartz, phosphate, etc.) will be carried in the water stream toward the outside.
