Traditional jigger is mostly the circumference eccentric drive jigger, which is not conducive to the loose of jigger bed and the proportion of stratification of mineral particles, which affects the sorting and recovery equipment. Saw-tooth wave series jigger is energy-saving gravity separation equipment developed and improved according to the law of layer theory of jigger bed stratification, and on the basis of traditional jigger. Its pulse curve is as saw-tooth waveform to make rose water faster than the dropped water; enhanced the loose of bed, eased the inhaled role, so that heavy particles in the mineral can fully settlement, greatly improving the sorting capacity and recovery rate of equipment. Its industrial test compared with the sine wave jigger:

High capacity

High concentration ratio and high recovery

Fabricated with highest quality material

Easy to install, operate and maintain

The pulsation curve is saw-tooth wave shape facilitate heavy mineral to settling

Saving water 30-40% than ordinary jig

The pulsation speed very easy adjusted by regulator

Suitable for roughing and desliming

This machine Can achieve a good result in processing such as placer gold, tungsten, iron, tin, hematite, cope, tantalum-niobium, titanium, manganese, barite, zirconium, chrome and gemstone etc.

saw-tooth Jig operating recovery rate is higher than the sine wave by the sn: 3.01%, w: 5.5%, pb: 1.63%, zn: 2.04%; water consumption reduced by 30% -40%, covers reduction by 1/3, and the stroke is adjustable. The performance of Saw-tooth Wave Jig has reached the domestic advanced level, and is one of the ideal devices in energy-saving gravity separation.

Jig machines need water to work, and it loosens materials in vertical alternative water-flows, and it forms different layers of materials of different densities and discharges both layers from up and down discharging ports separately. The basic composition of jigger is jigging chambers, also called jigging boxes, and there are screens in each chamber.

Water and raw ore will be fed from one end of the jigger screen, the ore granules will move in the vertical alternative water-flows. Layers will be formed because of density difference of materials. The minerals with small density will be in the up layer and will flow together with the up pulp flow while material with bigger density will be in the down layer and will discharged from the down discharging port as jigging concentrate.
4.Application

Saw-tooth wave series jigger is one of the gravity separation equipment. It is of large capacity, wide range of sorting grain size, simple operation and maintenance, widely used as coarse or fine sorting machine in the beneficiation of gold, tin-tungsten, titanium, hematite, too, coal and other minerals.
