Abstract

Presented here is a novel electrostatic separating method of plastic mixtures. Separation takes place in a vibratory feeder equipped with an electric field separator. By using the method, we studied the separation of polyethylene (PE) from polyvinylchloride (PVC) particles after tribocharging. Tribocharging of the particles took place in a mixer with an impeller. The influence of electric field strength and amplitude of conveying surface on the separation efficiency was investigated. The purity of PE was 99.3±0.1% at the recovery of 86.5± 1.0%. The purity of PVC was 97.6±0.2% at the recovery of 91.1 ±1.7%.
