Factors Affecting Air Classifier Efficiency

It is also fairly well known that it is by far much more difficult to achieve high efficiency with dry classifying than with wet Hence it is highly desirable to create conditions for improving the dry air classifying methods so that the high energy consumption associated with producing fine dry powders can be minimized Particle Size Distribution The classifier feed particle size

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 As it is revolved in the slurry the spiral is constantly moving the coarse backwards the fine material
