Tower milling flotation machine

The utility model relates to a tower milling flotation machine which is composed of a tower machine body, a mixing screw body and a driving mechanism, wherein the driving mechanism drives the mixing screw body through a mixing screw axis. The utility model is characterized in that the tower machine body is divided into an upper and a lower parts which are a floating region and a floating while milling region, wherein the mixing screw body is arranged in the floating while milling region which is filled with milling medium; the upper part of the floating region is provided with an overflow trough, and the middle part is provided with an auxiliary floatation mixing impeller, and the lower part is provided with a gathering tough and a tailing ore removal opening. The utility model integrates the functions of grinding, assorting, pulp adjusting and roughing separation into entirety, and can proceed with synchronous flotation at the freshest floatability mineral particle surface when the floatability mineral substance is ground. The utility model has the advantages of simple structure, convenient use and extensive application prospect. The utility model can be widely used in the floating operation of the floatability mineral with the functions of reducing overgrinding material and secondary argillization and increasing separate recovery rate. The utility model can realize the flotation while grinding.
