What happens when a moving screen jigger reduces the acceleration rate, moving screen jigger because of the combination of high and low vibration of the jigging chamber bed screen mesh and water media activity, jigging beneficiation is the process of sorting ores according to density in a vertical variable speed media flow. Dynamic screen jigger because the jigging chamber bed screen high and low vibration and water media activity combined, followed by the bed layer to raise, the media to break the resistance. Dynamic pressure release, its positive acceleration rate immediately turned to reduce the tendency, the media positive rate continues to decrease, the media rate change lags behind the acceleration rate change 90 ° (π / 2). Media acceleration rate down to 0, the media get back up rate.

In the process of jigging, the degree of flow of the jigging chamber constituted by the flushing water and top water. The degree flow of the medium can not only crowd out the light material, but also plays a sorting sensation, that is, the drift and settlement activity of the particles. This method is suitable for the disposal of gold ores containing clay. It contains rupture, grinding, fragmentation and stage beneficiation. Its characteristics are, the ore first by scrubber crushed scattered, scrubber fine-grained products by stage re-election and grinding, re-election adopted jigger sorting, jigger tailings into the classifier classification, classifier overflow and scrubber mud as tailings discarded, classifier sediment and scrubber coarse-grained products with a sieve rupture machine to stop the second rupture, rupture products into the stage of the stage of milling and stage of the sorting circuit. Jigging beneficiation is the process of sorting ore by density in a vertical variable speed media flow. Jigging cycle, the media rate is under the influence of the acceleration rate, the regular continuous change. The bed of the entire tray up, in fact, is not in the media back up rate is greater when the realisation.

The particle settling process is in the pre-lift flow continuous start. Media acceleration rate is the key identity of the resolution of jigging sorting. Equivalent density effect and particle drift settlement, composed of the jigging mechanism, the two kinds of sensing the opposite, mutual control. Medium positive acceleration rate and its attenuation gradient, the resolution of the sorting consequences, the medium of the flush, the amount of top water to resolve the disposal capacity, but also each other, mutual influence, mutual constraints.
