IMPROVING THERMAL PROPERTIES OF OIL LUBRICANT USED IN PARTIAL JOURNAL BEARINGS OF ROTARY KILN FOR KUFA CEMENT PLANT BY ADDING GRAPHITE GREASE
Abstract
Bearings generally suffer from high temperatures under loads, which leads to heat transfer problems between shaft and journal bearing. in this paper graphite grease mixed with oil used in journal bearing in three weight fractions 15%, 20% and 25%. physical properties such as thermal conductivity, viscosity and density would be measured. in cement plants, the effect adding graphite grease to the oil on temperatures of tier, roller, oil, shaft inlet and shaft exit would be measured. Also, SEM images of three concentrations of graphite grease in oil would be investigated.
