The invention relates to a dual-action composite water and air hybrid concentrating machine which comprises a rear axle lever assembly, an upper frame combination, a middle frame combination, a lower frame combination and a front axle assembly; the upper frame combination, a middle frame combination and a lower frame combination are arranged from top to bottom, the rear axle lever assembly is positioned at ends of the upper frame combination, the middle frame combination and the lower frame combination, and the front axle assembly is positioned at the other ends of the upper frame combination, the middle frame combination and the lower frame combination. The invention has the beneficial effects that: the ore removal production and quality can be conveniently handled through a quality observation window to effectively avoid ore loss and realize simple operation. The dual-action function (driving and driven) is finished through the front axle and rear axle lever assemblies, the concentrating speed is directly improved by 8-15 times comparing with a common simple gravity rinsing concentrating machine. Meanwhile, the load of the machine is effectively reduced and the production cost is greatly reduced. The pressure is generated through an air suction device, a water inlet tube, a water-air hybrid separation ore impurity box and a seal booster soft cushion, and the ore separation rate and quality are directly improved.
