Abstract
Abstract
An overview of the classification systems in hydrocyclones in the copper ore enrichment departments at KGHM Polska Miedź SA was presented. In recent years, IMN has been conducting an investment - replacing hydrocyclones with modern HC hydrocyclone solutions - manufactured by ZAM Kęty and IMN. The results of implementing modern hydrocyclones are presented. The important issue is to define relation between values of pressure and/or hydrocyclone feed density and cut point achieved in these conditions for chosen classification node By disposing this relation, implemented to classification monitoring system is possible to maintain cut point value within the range ± 5 % of assumed value by preserving acceptable feed variation in industrial conditions: - change of suspension density ± 20 % in ratio to assumed value, - change of feed particle size d80 ± 15 % in ratio to assumed value.
