Tribo adhesive separator (TAS) permits the separation of fine-grained bulk or crushed mineral materials (abrasive powders, industrial waste, ore, etc., etc.) due to the adhesion of the powder material different to the material rolls. When separating particles on the TAS according to the electrical properties, chemical composition, size, density different electrical charges produced and distributed in various hopper.
When triboelectrostatic methods charged particles when dispersed, impact and friction with the surface of the device; heterogeneous particles are charged the same magnitude but different in sign. Some components of the mixture are polarized, while others remain uncharged.
