摘要 |
The invention relates to a flotation machine, particularly to a flotation machine rotor, that is used for dispersing air, supplied via the rotor axis, to the surrounding slurry, and in which rotor there are formed alternating air ducts and slurry grooves, so that the end of both the air ducts and the slurry grooves, projecting outwardly from the rotor, form the outer surface of the rotor. According to the invention the air ducts (3, 15) are arranged in the rotor at essentially equal distances, starting radially from the rotor outer surface, so that the air ducts (3, 15) form in the center part of the rotor a space (6, 17) for the slurry, in which space the slurry surrounding the rotor is to be made to flow along the slurry grooves (5, 16) provided in between the air ducts (3, 15). |
