Spiral Classifier for Mineral Processing

2015-8-6  View ALL our Spiral Classifiers Models. 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 Classifier Mineral Processing

2020-7-9  Spiral classifier is widely used in beneficiation plant to match with ball mill to form a closed circuit circulation path to distribute ore sand. Filter the material powder milled in the mill, and then use the spiral piece to screw the coarse material into the ball mill inlet, and the filtered fine material is discharged from the overflow pipe.

Improving spiral performance using circuit analysis

1998-11-1  Spirals have become one of the most popular methods for treating fine coal. Unfortunately, spirals tend to produce an undesirably high specific gravity cut point and often misplace significant amounts of coal and/or rock. In the present study, a process-engineering tool known as linear circuit analysis was used to identify problems with traditional spiral circuits and to suggest alternative
