Abstract

ABSTRACT
In cement factories abrasive contaminants cause severe wear of moving surfaces leading to rapid failure of the machine elements. In the present study, talc used as solid lubricants dispersed in lithium grease. The effect of main components of white cement such as sand, kaolin and limestone contaminating lithium grease on friction and wear of test specimens was discussed. The tests were carried out using cross pin wear tester to determine both of friction coefficient and wear.
 
Based on the experimental results it was found that lithium grease should be dispersed by 30 wt. % oil to balance the contaminants and get the lowest friction and wear values. As the oil content, added to the grease, increased friction coefficient and wear slightly decreased. Besides, sand displayed the highest friction and wear values followed by kaolin, while limestone showed the lowest friction and wear. Friction coefficient generated from the action of the mixture showed relatively higher values than limestone and lower values than sand and kaolin. Friction coefficient and wear slightly decreased with increasing talc content.
