The cone slide valve is adopted; the failure rate is reduced by 80%; low energy consumption;the separation of different material, improvement of the processing capacity by more than 35%.



Stroke and jig frequency are easy to adjust; The advanced frequency conversion speed control technology is convenient to operate and manage; Small cover area, high processing capacity per unit area.
Sawtooth wave jig is revised and manufactured, based on the stratified theory and the adequate analysis of other conventional jigs. The jigging pulsation curve----produced by sawtooth wave jig----is in the shape of sawtooth wave which makes upward water flow quicker than downward water flow. The feature that upward time is shorter than downward time solves the problem that time and action of upward/downward water flows. This breakthrough dramatically amplifies the loose degree and mitigates suction action, which facilitates precipitation of coarse ores and improves ore recovery rate.
A tungsten ore dressing plant in Jiangxi is located in the mountains, the workSHOW area is small, the requirement for jig is much more strict in gravity separation process, according to the hierarchy law of the jigging bed theory, Xinhai developed and researched based on traditional jigging machine, the separating medium adopted digital electronic control system and electric controller air valve composed of transmission mechanism, successfully suit to this tungsten plant. In operation process, the productivity of light product is up to 60%, so failure rate is almost zero.
