Abstract: The electrical drum-type separator for separating a mixture of electrically non-conductive and conductive particles, comprising a housing (1) having a drum (3) mounted therein for rotation about a vertical axis, serving as a precipitation electrode, means (5) for feeding a mixture of loose materials onto the peripheral surface of the drum, at least two corona-discharge electrodes (10) for charging particles of the mixture of loose materials in the electric field set up between each corona-discharge electrode and a portion of the peripheral surface of the drum (3), and brushes (15) for sweeping non-conductive particles off the peripheral surface of the drum, equalling in number the corona-discharge electrodes.
