OPERATING CONDITIONS OF SLIDE BEARINGS OF MILLS USED IN KGHM POLSKA MIEDŹ S.A.

Abstrakt

The paper contains the results from a tec hnical analysis of the conditions of the operation of hydrodynamic bearings supporting the drums of ore processing mills at KGHM Polska Mied ź S.A. A theoretical analysis was performed on the grounds of onsite examination and measurem ents of principal dimensions of the bearings of interest. The computer simulation covered the characteristics of the oil film in the bearings as a function of bearing clearance, load, lubricant viscosity, and journal tilting in relation to two planes (horizontal and vertical). The results of the analysis indicate that the bearings currently operate close to maximum capacity and that there is a significant deflection of the bearing journals under the applied joint load of the drum’s own weight and the process load of grinders and slurry. The current extent of tilting can cause oil film breakage at the bearing’s edge. The result of calculations amended by bearings’ examination and measurements allowe d the formulations of conclusions regarding the current state of the bearings and evaluated load conditions. Guidelines were established for late r developments in the capacity and reliability of the bearings.
