This paper will address key measurements, analysis, adjustments, lubrication and continued monitoring that, when applied to lime recovery kilns in the Kraft pulping industry have resulted in increased kiln operational reliability and decreased component wear. There are six primary areas of mechanical interaction on a rotating kiln. 1. The tire and support roller interaction 2. The tire ID and shell interaction 3. The roller shaft and bearing liner interface 4. The roller bearing thrust mechanism 5. The thrust roller and tire interface 6. The pinion and main gear interaction We will discuss proper proven techniques for measurements of these key interaction points followed by data evaluation and adjustments which when combined, minimize operational stresses and direct wear to high capital parts. The integration of support roller thrust load measurement and ovality into kiln alignment procedures are key in maximizing kiln stability. Verification of support roller slopes and alignment of bearing housings to roller shafts are additional measurements that must be considered and corrective actions taken to further complete the process. Evaluation and possibly upgrades to lubrication type & application support the maintenance of kiln stability. Finally, periodic repetition of this process will significantly aid in overall maintenance planning and avoidance of unplanned component failure and associated downtime. Please note that much of the information contained within this paper has been presented in standard reference papers but not within this format or directed toward this audience. [1, 2]
