Abstract
An electrostatic free-fall separator has a feeding arrangement located upstream of the separator for feeding of fine-particle material to be separated into the electrostatic free-fall separator, wherein the feeding arrangement is formed as a funnel with braking inserts of an electrically insulated material and has walls limiting at their lower edge a longitudinal outlet slot, wherein the funnel has an inlet which is formed by one wall portion which is parallel to the outlet slot and an opposite inclined guiding surface with a lower edge extending parallel to the one wall portion so as to limit simultaneously a passage leading to the outlet slot, and two substantially vertical electrodes are arranged below the passage at a distance from one another which is smaller than the width of the passage.
