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.

An empirical model of the Kelsey Centrifugal Jig is presented. The model describes the partition of feed material to the jig concentrate, taking account of the main jig operating parameters: g -force, ragging characteristics and stroke length and of the material properties of the feed. The model has been tested against the laboratory-scale jig ...

High G-Force Gravity Concentrators. The higher the G-force, the smaller the minerals you can recover with a given technology. All of the Falcon Gravity Concentrators are high G-Force devices that achieve forces from 100-600Gs. When these forces are applied to a mineral feed, particles as fine as 3 microns in size can be selectively recovered.

The Altair centrifugal jig (formerly known as Campbell jig) is one such enhanced gravity concentrator, which is of a simpler design in comparison to its competing technology, the Kelsey jig. After being invented in 1971, the Altair jig has gone through several rounds of design modifications partly due to the recommendations of past studies ...
