Gravity Separation Equipment: Alternatives for Fine Coal …
Commercially available units include the Falcon Concentrator, Kelsey Jig, Knelson Concentrator and Mozley Multi-Gravity Separator. These devices, which were originally developed in the minerals processing industry, are capable of upgrading particles once believed to be too fine for water-based gravity separation equipment.
Altair Centrifugal Jig
The Altair Centrifugal Jig is one such enhanced gravity concentrator, which is simpler in design with a lower number of moving parts than its competing technology, i.e., Kelsey Jig. Originally invented in 1971 by Thomas Campbell, the Altair Jig technology has been modified over the years to be able to achieve an enhanced gravity field of nearly ...
