Jig is one of the main methods of gravity beneficiation beneficiation, which is widely used in coarse, medium, fine-grained ore gravity separators, such as limonite, hematite, manganese and other minerals weak magnetic sorting, and galena tungsten ore, tin, gold, antimony ore and other metal mineral separation. There barite, fluorite, lapis lazuli and other non-metallic mineral sorting areas, dressing better. Jigger working principle is: the proportion of mineral particles so that the different groups in the vertical movement of the medium according to the proportion of stratification, a large proportion of mineral particles located in the lower, which is heavy product (concentrate); a smaller proportion of mineral particles Located on the upper, which is light products (tailings). Jig trapezoidal sawtooth profile: Sawtooth jig jig bed is based on the law of development of a theory of stratification saving equipment re-election, sawtooth jig beneficiation, in addition to a very fine material, almost can handle a variety of particle size of mineral raw materials. Its pulsating jig sawtooth curve so that the water rises faster than the decline in the flow, and enhance the degree of loose bed to ease the suction effect, so that the weight of the mineral ore particles are fully precipitation, greatly improving the capability of the device than sorting and recovery, and adjustable stroke, thanks to electromagnetic speed motor, variable speed drag so red times. By comparison with the sine wave jigger their jobs than the sine wave jigger recovery were higher Sn: 3.01%, W: 5.5%, reduce water consumption 30 to 40 percent. As ore enrichment, roughing and selection operations, sawtooth jig is widely used in low-grade manganese ore, limonite grade and recovery of river sand to improve the useful minerals, such as gold, tungsten, tin, manganese, iron , lead, zinc, and other metals, efficiency significantly.
