The invention relates to a rotor (1) for a flotation machine for dispersing air into slurry around the ro- tor, the rotor comprising a body (2) equipped with a set of blades (3). The body (2) is assembled from ra- dial sector modules (9). The rotor comprises fastening means (10) for joining the sector modules (9) to each other. In the method for forming a rotor, radial sec- tor modules (9) are produced, and the rotor body (2) is assembled from a number of sector modules (9). Fi- nally, in the method for maintenance of a rotor, a damaged sector module (9) is detached from the body (2) and replaced by a defect-free sector module. |
