Spiral Classifiers - 911 Metallurgist

Normally, it is considered best practice to use a Hydroclassifier for separations at 100 mesh and finer. Efficiency of separation in fine mesh range requires a very large pool area. Thus, the Hydroclassifier, with its large surface area gives more efficient classification, more economically, than is possible with a “spiral” classifier.

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...
