Abstract In this study, a three-level Box–Behnken factorial design combined with response surface methodology (RSM) for modeling and optimizing of process parameters of high-tension roll separator (HTRS), namely feed temperature, feed rate and roll speed for the separation of titanium bearing minerals (ilmenite and rutile) was developed. Second-order response functions were produced for the ...
The high-tension separators are conventional ionized field separators utilizing a grounded roll to neutralize the charge of the feed material, which was passed through high voltage ionizing field. The conducting particles loose their charge to the grounded roll and follow a trajectory depending on the
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.

With high tension separators, the important forces are the image force F i and the centrifugal force. Equating these forces yields the pinning factor ... electrostatic separation is used again to remove residual conductors from the zircon and induced roll magnets are used to separate traces of monazite and staurolite from zircon.
High-tension Roll Separator In practice high tension separators are arranged in series to separate minerals through a combination of the effects of pinning and lifting. The important variables on high tension separators include; • Particles size (usually 60-500μm). Surface charges or unit mass on a coarse grain are lower than on a fine grain.
Jul 26, 2010· The high-tension separators are conventional ionized field separators utilizing a grounded roll to neutralize the charge of the feed material, which was passed through ionizing field. The conducting particles lose their charge to the grounded roll and follow a trajectory depending on the centrifugal force developed by the speed of the rotor as ...
CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Through the development of innovative in-line mineral quantification sensors, the possibility has arisen to apply modern control theory to implement automatic process control for electrostatic high tension ("HT") roll separators. A pilot-scale set-up was constructed to enable continuous tests to be carried out.
cleaning with high tension roll (HTR) separators • After ilmenite removal, the final non-magnetic stream was subjected to traditional processing methods to generate rutile and zircon products. A simplified process flowsheet for the ilmenite circuit products is depicted in Figure 4.
All the tests were carried out on a roll-type laboratory separator (roll diameter: 250 mm; roll speed: 175 r/min), provided with an over-tray heater, to ensure the thermal conditioning of the samples at +120 C, and a system of high-voltage electrodes, consisting of a needle-type corona electrode and either a second corona electrode or a tubular ...
The high tension belt separator is a variant of the high tension roll separator described above. Feed particles are dispersed evenly across the width of an electrically grounded conveyor belt. Particles are charged, usually by a negative corona, although other mechanisms of charging are possible.
