DOVE Spiral Classifier, also referred to as Screw Classifier, or Spiral Mineral Separator, is highly efficient classifier designed for closed circuit wet classification and separation of the Slimes (Fines) from a sandy sized (Coarse) material. It is well suited for classification, where a two product size-split is required. Due to inherent operational qualities, DOVE …
The spiral classifier rotates at a low speed through the spiral to stir the pulp to make the fine particles suspend to the top and overflow to the overflow . In contrast, the coarse particles sink to the bottom of the tank and are conveyed to the discharge port by the screw to be discharged as returned sand, while The hydrocyclone needs to ...
spiral classifiers -considering theirapplications and costs. Although in use for decades in the mining industry, spiral classifiers have lost a lotoftheirimportance due to the development ofcyclones. This trend, however, is now being reversed, and in the last few years there has been an increasing interest in spiral classifiers, in view oftheir
Spiral classifier is used for material classification with spirals used to stir and convey materials according to the difference in material settling velocities. It is a …
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 & …
