·Spiral classifiers This classifier uses a continuously revolving spiral to move the sands up the slope They can be operated at steeper slopes than the rake classifier in which the sands tend to slip back when the rakes are removed Steeper slopes aid the drainage of sands giving a cleaner drier product
·Unlike the rake and spiral classifiers the overflow of the cyclone is the exit point for the fine material instead of the other way around as it is in the case of the other two Extending from the overflow discharge into the body which is the feed entry point of the cyclone is the VORTEX FINDER
The spiral classifier was originally developed for closed circuit grinding It has since been applied very successfully to other classification duties where a two product size split is required Inherent operational qualities of this classifier make it ideally suited for sizing washing or dewatering materials such as ores phosphate rock sands coal oyster shells solar and potash salts
