Abstract
The static electric field is used in many industrial processes, such as electrostatic separation process. One of the devices that uses a difference in electrical properties of the particles is drum separator. In this device, particles of varying conductivity are electrified in the corona zone and fall on the drum. The particles of high conductivity lose their charges and brake off the drum while the particles of small conductivity keep their charges and are held on the drum surface. To determine the effectiveness of separation is necessary to determine the particle trajectories. Trajectories of separated particles are affected by many factors, among which the most important are: the electrodes configuration, value of high voltage (both factors determine the distribution of the electric field between the electrodes). The article presents the results of analysis of a distribution of the electric field in the drum separator for different configurations of electrodes and the applied voltage.
