High tension electrostatic separators are specially designed for the separation of titanium-bearing mineral sands, hard rock ilmenite and rutile, cassiterite, tantalite, wolframite, iron ore, and plastics from metals in waste recycling systems. These machines take advantage of the differences in electrical conductivity between various minerals within an ore feed. The high-tension roll electrostatic separator (HTR) uses a grounded roll to transport the feed material through a high-voltage ionizing field (corona). Particles become charged through ion bombardment. Conductive particles transfer their charge to the grounded roll and are thrown off by centrifugal and gravitational forces, while non-conductive particles remain pinned to the roll surface and are released either through charge dissipation or mechanical means such as brushes and high-voltage AC wipers.
The throughput capacity of a high-tension electrostatic separator is closely related to the roll speed, roll width, and characteristics of the feed material. For smaller diameter rolls, a higher rotation speed is needed to maintain a good feed rate. However, at higher RPMs, coarse, non-conductive particles may leave the roll surface too early due to increased centrifugal force, leading to misplacement in the conductor stream. Conversely, under low RPM conditions, fine conductive particles might not gain enough inertia to be thrown off, causing misplacement in the non-conductor stream. Therefore, for processing particle mixtures with varying physical properties—including conductivity, particle size, and density—it is essential to adjust the roll speed and electrode positions to optimize the overall process.
