CENTRIFUGAL JIG

摘要

An improved jig screen 10 for a centrifugal jig includes a recovery zone 30 and a stratification zone 20 adjacent to one another. The stratification zone 20 is co nstructed to prohibit outward radial passage of slurry particles while permitting fluid pulsa tions to be imparted to the slurry during jig screen 10 rotation. The stratification zone 20 axially leads to the recovery zone 30. The recovery zone 30 has openings permitting passage of particles in the slurry and through which fluid pulsations are directed to the s lurry during jig screen 10 rotation. The combination of applying centrifugal force and fluid pulsations to a pre-stratified slurry more effectively separates the heavy particles passin g through the recovery zone 30 of the jig screen 10 from the lightweight particles discharged at its exit end.
