JT sawtooth wave jig is a new type of jigs. It is one of the types of modern gravity separation equipment. New it has formed series whose use is expanded. Such type of jig uses electromagnetic stepless speed regulation which features even rotation, smooth ore current, strong adaptability to selected materials, good separation effects of medium and fine grains, and water saving. Since such jigs have large handling capacity and wide range of sorting particle sizes as well as are easy for operation and maintenance, they are mainly used to sort alluvial gold, tungsten ores, tin ores, hematite, and beach placer.

For the jigs, the bottom surface of the frame must be installed horizontally to ensure the gradient of the screen in the tank is within the design scope.

Technical Parameters

Traditional jigs mostly adopt circumferential off-center drive. Their jigging pulsation curves are mostly sine waves. The ascending and descending water flow velocity and action time produced by septal movement are basically the same. These hinder the loosening of jig beds and layering of ore grain according to gravity. Therefore, the sorting ratio and recovery rate of equipment are affected.

Sawtooth wave jigs are a kind of energy-saving gravity equipment development and improved on the basis of traditional jigs according to the theoretic layering law of jig beds. Compared with sine wave jigs through industrial tests, the recovery rate of sawtooth wave jigs are higher than that of sine wave jigs respectively in Sn:3.01%, W:5.5%, Pb:1.63%,Zn:2.04%. The waterconsumption is reduced by 30%to 40%. The area of flooring area is reduced by one-third and the stroke can be adjusted. Since electromagnetism governing-speed motors are adopted for dragging to enable the jig frequency to be steplessly regulated and their parameters reached advanced domestic level, such jigs are one of the ideal types of energy saving gravity separation equipment.
