The useful model refers to the grinding blades 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). Under the attackingedge (6) and parallel to the inside grinding blade (5), in the zones with intensive local wear (7), near the hub (1) and the front disk (2), are mounted additional wear-resistant elements (8) reinforced by straps (9). The advantage of the fan mill rotor according to the useful model is that with appropriate arrangement of the additional wear-resistant elements is extended the run between repairs. |
