In the process of hydroclassification of file-dispersed mineral resources (especially in large-capacity closed spherical grinding circuits), hydrocyclones are more useful than screens because of their high productivity, lesser water consumption and reaching of required consolidation of pulp before flotation. At the same time, high-frequency vibration screens are more technologically efficient, because they divide material by one separating characteristic (grain coarseness) and exclude the cumulation of released fine grains with big density in composition of circulating load. Joint application of hydrocyclones and vibration screens makes possible to process large amounts of pulp with maximal efficiency of separation, moderate water consumption and required content of hard substance in final product of “grinding-classification” scheme.
