  • Rotary Kiln Maintenance Procedures

    maintenance is the stable alignment of the support rollers Roller positions must be consistent with minimum ovalities, low support roller thrust loads, and a straight kiln axis The preferred procedure to assure those conditions is a hot kiln alignment, where all alignment measurements are taken when the kiln is under normal operating conditionsThrust rollers are positioned on both sides of the tire at each pier, ensuring that the drum cannot drift longitudinally in either direction A drum riding too hard against any thrust roller is not only a sign that the drum is not floating properly, but may also indicate thatRotary Drum Training & Float Between Thrust Rollers3) Roller bearings are adjusted for minimal thrust load This assures very low thrust roller loads and low bearing temperatures 4) Shell runout measurements are taken as necessary to determine if “dogleg” conditions threaten kiln mechanical stability 5) A kiln alignment is not complete without considering the effect of roller slopes on kilnHot Kiln Alignment Technology anioncorp
