Sawtooth jig | Sawtooth wave wave jig | mineral jig

1、 Overview

Sawtooth jig | Sawtooth wave wave jig | mineral jig is one of the key equipment for gravity beneficiation. Because of its large processing capacity, wide sorting particle size range, high recovery rate and good effect, the sawtooth jig | Sawtooth wave wave jig | mineral jig is widely used in the sorting of placer gold, tin, tungsten, lead, zinc, antimony, manganese, diamond, iron ore and other non-ferrous metallurgical mines and gold mining ships. The JT4-2 and JT1.5-2 Sawtooth wave wave large particle jigs in this kind of products can feed ores with a maximum particle size of 30MM, and discharge ores on the screen and below the screen. It is applied to the beneficiation of Baryte ore, manganese ore, iron ore and other ores, and has the advantages of wide ore feeding particle size range, significantly reducing the amount of make-up water under the screen, etc.

2、 Working principle

Traditional jigs are mostly driven by circular eccentricity, and their jigging pulsation curves are mostly sinusoidal. Due to the fact that the rising and falling water flow velocities and action times generated by diaphragm movement are basically the same, it is not conducive to the loosening of the jigging bed layer and the stratification of ore particles according to specific gravity, thereby affecting the equipment's sorting ratio and recovery rate.

Sawtooth jig | Sawtooth wave wave jig | mineral jig is an energy-saving gravity separation equipment developed and improved on the basis of traditional jigs according to the theoretical layering law of the jigging bed. Its jigging pulse curve is zigzag, making the rising water flow faster than the falling water flow: the rising time is short, and the Fall time is long; Overcoming the defects of sine wave and pulsating curve jigs that generate rising and falling water flow with the same action time, enhancing the bed's looseness, alleviating the suction effect, and allowing the heavy ore particles in the minerals to fully settle, greatly improving the equipment's sorting capacity and recovery rate. Compared with the sine wave jig, it has increased Sn 3.01%, W 5.5%, Pb 1.63%, and Zn 2.04%, respectively; The water consumption is reduced by 30% -40%, the floor area is reduced by 1/3, and the stroke is adjustable. Due to the use of electromagnetic adjustment motors for dragging, the stroke can be adjusted steplessly. Its performance has reached the advanced level in China. The sawtooth jig | Sawtooth wave wave jig | mineral jig is one of the ideal energy-saving gravity separation equipment at present.
