ABSTRACT:
A mechanical flotation machine comprises a flotation cell, a circulating pipe vertically installed therein, an axial impeller mounted in the lower portion of the pipe and a guide device secured to the lower end of the pipe. The guide device has an annular gap through which pulp flow generated by the impeller returns from the cell to the pipe. Vanes are installed in the annular gap to create, above the impeller, pulp flow rotating opposite to the rotation of the impeller.
