  • Spiral classifier or hydrocyclone Grinding & Classification Circuits

    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 &When spiral classifiers for sand washing and dewatering, the production capacity is generally calculated according to the amount of sand returned, and the control particle size and allowable feed flow rate are checked according to the overflow speed 2Hydrocyclone Hydrocyclone is a type of classifier that is for the fines classification6 Solidliquid separation methods and equipments
