Abstract

ABSTRACT
The operating environment in cement industry is particularly severe in terms of the high ambient dust concentrations. During the severe working conditions dust concentrations of the order of 100 to 500 times higher than the normal may be encountered. The present work aims to develop the abrasion resistance of moving surfaces of machine elements lubricated by contaminated greases. The intended development is to disperse lubricating greases by polymeric thickeners in powder form, such as polytetrafluoroethylene (PTFE), polymethylmethacrylate (PMMA), high density polyethylene (HDPE) and low density polyethylene (LDPE).
 
Wear resistance of cylindrical steel specimens was examined using a cross pin wear tester. Experiments were carried out using clean and contaminated lubricating greases. The contaminants in the cement industry such as sand clay, air cooled slag (high ferric particles), air cooled slag (low ferric particles), iron ore, limestone, fatty clay and water cooled slag (with medium ferric particles) were added to the grease at a concentration of 10 wt. %.
 
The results showed that wear caused by the tested contaminants can be reduced by dispersing the lubricating greases by HDPE and PTFE. LDPE and PMMA showed the relatively lower wear resistance than that observed for HDPE and PTFE.
