Nov 01, 2004 The Kelsey Centrifugal Jig is an enhanced gravity concentrator capable of separating fine minerals andor minerals with relatively small differences in specific gravity. Since the first commercial installation at the Renison Bell tin mine in Australia, development and improvement in hardware has continued, including the introduction of the high-capacity Model J1800 Kelsey Jig.

An improved jig screen for a centrifugal jig includes a recovery zone and a stratification zone adjacent to one another. The stratification zone is constructed to prohibit outward radial passage of slurry particles while permitting fluid pulsations to be imparted to the slurry during jig screen rotation. The stratification zone axially leads to the recovery zone.
Kelsey Jig Technology Get Latest Price Mineral Technologies designs, manufactures and supplies the Kelsey Centrifugal Jig which extends the efficient size recovery range of fine mineral separation processes to 10 microns by combining the principles of conventional jig technology with centrifugal
The centrifugal jig of claim 11, wherein the stratification zone along the jig screen has a flexible interior lining. 14. The centrifugal jig of claim 11, wherein the stratification zone along the jig screen has an interior lining that is permeable, the openings of the permeable lining preventing radially outward passage of particles in the slurry.
If the hutch of the Hartzjig is turned from a horizontal to a vertical orientation Figure lb and spun about an axis, we then have the basic operating principle of a Kelsey centrifugal ig The jig hutch design for the model J650 and more recently the model J 1300 Kelsey jig
A centrifugal jig of the type in which a feed slurry is introduced into a container rotating about a vertical axis in a region radially bounded by a screen. The screen is preferably substantially parabolic in shape. Ragging is provided on the screens inner surface and water is provided in the hutch region on the opposite side of the screen.
Renison Limited has installed the worlds first commercial production application of the modell J650 Kelsey centrifugal jig into its gravity concentration circuit. Laboratory, pilot plant and commissioning work are described together with summaries of experimental and production data.
May 01, 1994 CONCLUSION Model J650 Kelsey centrifugal jigs are an efficient and clearly superior gravity separation machine when compared to historical performance at Renison Limited. Model J1300 Kelsey jigs, although at a very early stage of evaluation, have also performed extremely well and incorporate many design improvements developed in the J650 model.
Dec 02, 2016 Kelsey said the device took about 10 years to perfect to that level. De Hoog said the jig lent itself particularly well to dealing with tin. At one stage it was processing about one quarter of the worlds tin, he said. Besides tin the Kelsey Jig has also been applied to mineral sands, gold, nickel, tantalum and wolframite.
Kelsey Centrifugal Jig was found to be promising for the beneficiation of fine iron particles. The present study was carried out to have a better understanding of the separation process of Kelsey Jig through detailed experimentation. Beneficiation of fine iron ore fines was studied in Kelsey Jig. A constant pulp density 25 solids of the feed slurry was maintained in the study.
2 For example Centrifugal jigs. An example of a centrifugal jig is the Kelsey jig, manufactured by RocheMT. This incorporates the pulsing action, water injection and the use of a ragging medium and internal screen of a conventional, but in addition centrifugal spinning motion to

The Kelsey jig is an appropriate substitute to the conven-tional jig with some basic similarities. The parameters of conventional jig are entirely utilized along with addi-tional features to vary the apparent gravitational field. The ability to increase the apparent gravitational field enhances the chances of recovery of fine particles by
Mar 01, 2021 Kelsey jig is found to be superior to spirals, and Altair jig for treating ultrafine, which establishes that centrifugal separation is superior to conventional gravity separation. Kelsey jig can be a substitute for the conventional gravity separator for a size range of 2000 37 m coal fines at a combustible recovery of 96.9 with ash ...
The Kelsey centrifugal jig. The Kelsey centrifugal jib was invented by Christopher G. Kelsey of Australia and patented in Australia in 1985 PH9037, PG0122 and 1990 in the USA US 4,898,666. The first commercial sale was of a lab-sized machine in 1989. Geo Logics Inc developed the device, and automatic screen cleaning was introduced in1999.
Jun 23, 2013 Kelsey Centrifugal Jig was found to be promising for the beneficiation of fine coal particles. may be overcome using the relatively new genre of enhanced gravity separators. . The major advantage of enhanced gravity separation is its ability to reject composite particles more efficiently zircon recovery from plant tailing.
That is why the centrifugal jig concentrators Kelsey works better than any centrifugal concentrator. unknown 6 years ago unknown 6 years ago. Like. With diamonds, rubies, gold, COLTAN, tin etc. There is absolutely NO need to classify into different size fractions before jigging. I understand the theory, but in practice hindered settling for ...

Abstract This invention relates to a centrifugal jig comprising a rotating device, at least one jig unit and a product receiver. The jig unit includes a hutch chamber, a screen residue chamber, a screen, a feeding device, a discharging device and a pulsator. The jig unit is installed on the rotor at an inclined angle along the movement of the feed.
The Kelsey centrifugal jig is a significant departure from the conventional jig albeit some basic similarities. It utilizes all the parameters of conventional jig as well as the additional feature to vary the apparent gravitational field. The ability to increase the apparent gravitational field enhances the recovery of fine particles by improving
