FUNdaMENTALS of Design
In general, sliding contact bearings do best when the materials in contact are dissimilar: A steel shaft should not run in a steel bore, but it can run in a bronze lined bore (eg, a bronze bushing) If similar materials must be used, such as often the case in construction e quipment where a steel pin runs inside a...

Rod mills, how they function
Rod mills are very similar to ball mills, except they use long rods for grinding media The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 14 to 16...
