ABSTRACT:
The invention relates to a rotor of a flotation machine, particularly to a rotor, that is used for dispersing air to a slurry, and which rotor comprises alternating air ducts and slurry grooves and a collar fitted to the rotor for guiding the slurry flow into the interior of the rotor for avoiding undesired cross flow effect of the slurry flow. The rotor of the present invention efficiently prevents sanding effect and provides excellent dispersion of air into the slurry.
