Sawtooth wave jigger is a new type of jigger that appeared in recent years, which has changed the way of traditional jigger using eccentric linkage transmission method to drum the water flow to produce sinusoidal pulsation curve, the jigger pulsation curve is sinusoidal, the speed and time of the rising and falling water flow produced by diaphragm movement is basically the same, and sawtooth wave jigger is also named for this reason.

Sawtooth wave jigger adopts a sawtooth wave generator to push the lower moving cone of the jigger, so that the water flow generates regular movement and produces the pulsation curve of sawtooth wave. It has been proved that the sawtooth wave pulsation curve has the advantage of sinusoidal wave pulsation curve for the recovery of fine-grained materials, which effectively extends the lower limit of the effective recovery of grain size of the mining diaphragm jigger. Secondly, relevant research shows that the jigging effect of sawtooth wave jigger is better than that of sine wave jigger for unclassified materials in the range of particle size. In addition, after years of practical experience, it is found that the recovery effect of serrated wave jigger is also very significant for the recovery of irregularly shaped gold, such as flake gold and dendritic gold.

The advantages of sawtooth wave jigger are very obvious, especially in the recovery of fine-grained materials is incomparable to other jigging machines, but it also has great defects that need to be improved. Firstly, the sawtooth wave generator of the sawtooth wave jigger can not produce a larger stroke and higher stroke, which puts it in a disadvantageous position in terms of processing capacity, and can not reach the processing capacity of the jigger with the same jigging area. Secondly, the success of sawtooth wave jigger in fine-grained material processing contradicts with the processing of coarse-grained material, because it almost can't deal with coarse-grained material, not to mention the processing of 10-30mm coarse-grained material, the only way to deal with such coarse-grained material is to use AM30 jigger or 2LTC-912/4A jigger.

Sawtooth wave jigger has its inherent advantages and shortcomings, according to the advantages and disadvantages of the jigger and the nature of their own ore to determine the model, the subsequent beneficiation operations are of great help.
