High Tension Roll separator principle (3 replies)

Can anybody explain briefly about the HTRS(High Tension Roll separator) principle, here how the non conducting particles stick to the roll?

Very briefly the HTRS operates by giving the poorly conducting particles a high surface charge and this causes them to be attracted to the surface of the roll, a process called 'pinning'. Particles of higher conductivity do not become charged as rapidly and what charge they do gain is quickly dissipated meaning that they continue to follow their trajectory and are thrown away from the roll.

Laboratory high tension roll separation and the commercial machines available for this purpose are discussed. The shortcomings of these machines are indicated and a machine that overcomes some of these undesirable characteristics is described. A procedure for evaluating laboratory high tension roll separation is described. The use of this evaluation procedure in conjunction with the laboratory separation is described with examples taken from the Dunwich and Hexham processing plants of Associated Minerals Consolidated Limited. Evidence that laboratory testwork results may be directly transposed to operating plants is given.

A discussion of the effects of variables in high tension roll separation of mineral sand concentrates concludes the paper.

This is a great document I found on OneMine.org that I thought you might be interested in reading.
