JT Sawtooth Wave Jigger

JT Sawtooth Wave Jigger

The Sawtooth Wave Jigger is one of the devices of the modern gravity separation. For its large capacity and a wide range of sorting particle, simple operation and maintenance, Sawtooth Wave Jigger is widely used as a rough election or selection of sorting gold, tin, tungsten, titanium, hematite, coal and other minerals.

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. Sawtooth Wave 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.

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. Their jigging pulsation curves take the shape of sawtooth waveform which gets the ascending water to travel more rapidly than the descending water. The ascending time is short while the descending time is long. The problem that the ascending and descending water flow and action time produced by sine wave and pulsation wave are the same is solved. The looseness of the bed is strengthened and suction function is alleviated so that the heavy ore grains in the minerals are able to precipitate fully and the sorting ratio ability and recovery rate of equipment are largely improved. 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%, and Zn:2.04%. The water consumption 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.
