| Popis: | Impact wear tests were carried out in a laboratory simulating the working condition of balls against lining plates in ball mills in order to find the optimal combination of materials for balls and lining plates. The results showed that: (1) for the same plate material with increasing hardness of balls, the wear resistance of plates and the wear system (balls plus plates) increased; (2) for the same ball material with increasing plate hardness, the wear resistance of the balls and the system increased, too. Pilot tests were done in real ball mills in two fire power stations for pulverizing coal. The results were coincident with those obtained in laboratory tests. The optimal mating was high chromium cast iron ball mills working in ball mills lined with medium chromium steel plates. |
