An equipment realizes the separation of light and heavy mineral by the different sedimentation speed in vertical alternating water flow.Production capacity:1～25t/h.Product Improvement: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%.
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.
