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.

Dec 05, 2019· Own to the rotary kiln such as cement kiln, lime rotary kiln and shaft kiln is widely used in building materials, chemical industry, nonferrous metallurgy industry, black metallurgy, and refractory kiln''s support roller is an important module, and it has the character of large bearing load, poor working environment, constant running, and complex maintenance.
Concave and convex wear present the most common problem in kiln tire and support roller wear. In order to control the kiln axial thrust, the roller shafts are skewed and this procedure has a direct effect on the mating surface profile of the support rollers and the tire. The axis of the roller shaft is no longer parallel to the axis of the tire.
