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.

Spiral classifier or hydrocyclone - Grinding ...

2021-8-11  A friend familiar with this told me the main problem with spiral classifiers is the cut size is directly proportional to retention time (flow rate, Stoke's law, that sort of thing). To get a fine cut size requires flow of almost zero = the finer you want to cut, the lower the flow and density required. Hitzrot, H. W. wrote a great paper in Society for Mining, Metallurgy Exploration Mineral ...

Spiral Classifier - goldcilplant

With the aid of the principle that the solid particle size is different and the specific gravity is different, the settling velocity of solid in the slurry is different. The fine solid is discharged at the overflow weir,and the coarse particles sink to the bottom, driven by the spiral and discharge from the upper end of the classifier.
