The separation of HDPE/PPmixture charging on mentioned plates (except PVCplate) went ahead the same way. HDPE particles obtainedtheir negative charge and were attracted to positiveelectrode, whereas PP particles were chargedpositively and were attracted to negative electrode.The best separation of HDPE/PP mixture was reachedon HDPE plate. The recovery of HDPE in negativelycharged product was 90.88 % and recoveryof PP in positively charged product was 93.03 %.recovery of HDPE and PPto negatively chargedproduct [kV]10080604020093,73 95,37 96,168,5529,5816,3911,332,482,64 0,1725 30 35 38 40HDPE PPvoltage [kV]Fig. 7 Dependence of separation HDPE/PP mixture with particle size 1x1 mm on various electrodevoltage (charging plate is PET)
