Graded grains make finer flour28 Jan 2019 07:01
With the alljig® process the feed material is initially fluidised with pulsed water, with the grains graded according to density. The jigs separate the specifically lighter scheelite-poor yield from the specifically heavier scheelite-rich ore from the stratified material bed. The jigging motion used to separate the grains does not cause any wear and tear and is induced by adding air so the stroke movement (frequency, amplitude and waveform) can be adjusted across a broad range of operating parameters.
