jigger machine belongs to gravity-based equipments, which can separate mineral based on differing of specific gravity. Gandong saw-tooth wave jig is mainly consisting of three parts: main frame, driving set and jigging chamber.

jigger machine is widely used in gravity concentration of tin, tungsten, placer gold, hematite ore, manganese, titanium, antimony, lead, tantalum, niobium and other minerals.

The pulsing curve of the traditional jig is sinusoidal waveform, the up and down speed of water flow and acting time produced by the movement of membrane are almost the same, so it is unfavorable to loose of jig bed and layering of minerals based on special gravity, and thus affect separation ability and recovery rate. Saw-tooth wave is energy economy gravity equipment that is developed and improved from traditional jig on the basis theory of jig bed layering. Its jigging pulsating curve is similar to saw-tooth wave, which makes the up speed of water flow quicker than down speed of water flow, so it can improve looseness of jig bed and reduce suction action, which can lead to fully settlement of heavy particles in slurry; it highly improves separation ability and recovery rate. Stroke and frequency of stroke are adjustable.
