energy saving spiral classifier for grading ore slurry

Spiral Classifier for Mineral Processing - 911 Metallurgist

Aug 6, 2015 ... 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. As it is revolved in the slurry...
