Description

Technical Field

[0001] The utility model relates to the technical field of flotation machines, in particular to a mechanically stirred flotation machine. Background Art

[0002] Flotation machine is the abbreviation of flotation concentrator. In the process of mineral flotation, the pulp treated with reagents is added and then passed into the flotation box with stirring and aeration, so that some ore particles are selectively attached to the bubbles. The attached ore particles float to the surface with the bubbles, and finally the different ore particles are separated. Mechanically stirred flotation machines usually use stirring blades to stir in the flotation box. When working, the stirring blades rotate under the drive of the motor, and the stirring coverage area is circular. However, when a square flotation box is used, the stirring coverage area does not match the cross-section of the flotation box, and it is difficult to stir the edge position, which affects the stirring effect of the flotation machine.
