The possibility of converting flyash waste into a raw material for cement industry and other applications justifies the investigation of new beneficiation techniques, including those using electrostatic forces. The aim of this paper was to demonstrate the effectiveness of a modified rolltype corona separator in the processing of this material.
Abstract. The singlestage separation of fly ash from field 1 of the electrostatic precipitator of Reftinskaya GRES (Regional Thermal Power Plant), which burns coal from the Ekibastuz Basin, was performed by aerodynamic classification with the use of a flow of air.
