| Abstract: | Two MG290/470 type ball mills were allocated in thermal power plant of Luoyang Petrochemical Headquarters Factory. After putting into operation, abnormal noise is existing in varying degrees, and fracture phenomena of bolts on the jointed face of big toothed wheel have frequently occurred. It is believed from analysis that the said situation to be the result of big toothed wheel being deformed, and having not been repaired in time. After treatment of the big toothed wheel, the abnormal noise of said mills has been eliminated. |
