Mineral Processing System

Electrostatic Separation: The electrostatic separators are classified into two main types, such as electrodynamic separators or high tension roll separators and electrostatic plate and screen separators. Both the separators work in similar ways, but the forces applied to the particles are different i. E. Gravity and electrostatic attraction forces.
