Working Principle of Electrostatic Separators. Electrostatic separation, as the name suggests, works on the principle of charge differences. When subjected to an electric field, particles with different properties acquire charges at varying levels. Following this, the charged particles experience an electrostatic force in the electric field.

In the separation experiments, we selected two groups of particles: 30–50 µm and 75–110 µm. The mass of each group was 0.5 g. The size distribution of the two groups of particles were measured by the Mastersizer, which is shown in Fig. 14. In each experiment, 0.5 g of each group were mixed and fed into the board.
