Jigging

5.1.2 Principle of Jigging. The jigging operation is mainly actuated by alternate strokes of pulsation and suction. The particle bed resting on top of the screen starts dilating at the start of the pulsation stroke, and separation of particles occurs due to differential acceleration followed by hindered settling.
