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 conditions.
A roller chain is a series of connected journal bearings that articulate as they enter and leave the sprockets. This articulation results in wear on the pins and bushings. As material is worn away from these surfaces the roller chain will gradually …
