Jigger is one of the key equipments for gravity beneficiation. Because of its large processing capacity, wide range of sorting particle size, high recovery rate and good effect, it is widely used in sorting sand gold, diamond and iron ore and other non-ferrous metallurgical mines and gold mining ship. Applied to the beneficiation of barite ore, manganese ore, iron ore and other ores, it has the advantages of a wide range of particle size and a significant reduction in the amount of water replenishment under the screen. Traditional jigging machine is mostly circular eccentric drive, its jigging pulsation curve is mostly sinusoidal, due to the diaphragm movement produced by the rising and falling water velocity and action time is basically the same. Therefore, it is not conducive to the loose jigging bed and the separation of ore particles according to specific gravity, thus affecting the separation ratio and recovery rate of the equipment.

Jigger is a kind of energy-saving re-election equipment developed and improved on the basis of traditional jigger according to the theoretical stratification law of jigging bed. Its jigging pulsation curve presents a sawtooth shape, which makes the rising water flow faster than the falling water flow. Rising time is short, falling time is long, overcoming the sinusoidal wave, pulsation curve jigger produced by the rising, falling water flow and the same action time defects, enhance the looseness of the bed, alleviate the role of inhalation, so that heavy mineral particles in the minerals hood to the full settlement, and greatly improve the separation ratio of the equipment capacity and recovery rate.
