GRAVITY SEPARATING
Sawtooth Wave Jig
Principle
Sawtooth wave jig is one of the modern gravity concentrator equipment,
due to its great process ability, wide range of particle size classification, and
simple operation and maintenance, it is widely used in mineral roughing or
concentration of placer gold, tin, titanium, hematite, iron ore, coal, etc., es-
pecially in the fields of mineral processing of manganese ore and barite ore.
Traditional jigs are usually driven by circular eccentric force, the jig pulsation
curve of which is sinusoidal waveform. The speed and action time of the rise
and fall water currents produced by the diaphragm motion are the same,
therefore it is bad for the decompaction of jig bed and ore particle layering
according to the proportion so as to affect the classification ratio and recov-
ery.
Sawtooth wave jig is a kind of gravity concentrator equipment revised and
manufactured based on traditional jigs according to jig bed theories and lay-
ering rules. The jig pulsation curve is in shape of sawtooth, which makes the
rising water flow quicker than the falling water flow. The rising time shorter than the falling time solves the problem
that the speed and action time of the rise and fall water currents produced by the diaphragm motion are the same,
which strengthens the decompaction of jig bed, eases suction impact, makes full sedimentation of heavy ore particles
and enhances the classification ratio and recovery. Compared with sine wave jig, Sn is increased by 3.01%, W is in-
creased by 5.5%, Pb is increased by 1.63%, and Zn is increased by 2.04%; water consumption is reduced by 30% - 40%,
and covering area is reduced by 1/3. The adjustable stroke with infinitely variable control of jig frequency is driven by
electromagnetic adjustment of the motor, the property of which has reached domestic advanced level. Sawtooth wave
jig is one of the ideal energy-saving gravity concentrating equipment.
