The useful model refers to the rotor of a coal fan mill and finds application in the power industry. The rotor of the fan mill consist of a hub (1) connected with the front disk (2) by means of the basic blades (3), on which are mounted outside grinding blades (4) and inside grinding blades (5) that have an attacking edge (6), and zones with intensive local wear (7). On the hub (1), near the attacking edge (6) is mounted a protective ring (8). To the hub (1) and the protective ring (8) are fastened repellers (9), located at angles from 0 to 75 degrees in relation to the hub axis, oriented inversely to the rotor rotation direction. The advantage of the fan mill rotor according to the useful model is that by means of the repellers is avoided the local wear and in this way is extended the run between repairs.
