Kiln Trunnion Roller Resurfacing - NAK Kiln Services

Trunnion Roller Resurfacing Wear on the surfaces of the kiln tires and support rollers makes it difficult, if not impossible, to make support roller adjustments to achieve a proper alignment. An ideal hot kiln alignment involves not only the horizontal and vertical axis of the shell, but the balance of the axial thrust of the kiln as well.

Machine Design - Case No. 93: Misalignment Overload of ...

The mechanics did not realize that the rolling element of the trunnion that was removed had a taper on it. Thus, the new trunnion went in on an angle that created a tremendous thrust load, besides the misalignment. Bearing manufacturers indicate that spherical roller bearings are not that good in high thrust load conditions.

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 conditions.

The change in the alignment can be seen in the upper left picture. The yellow bars approximate the distance between the edge of the raceway and the edge of the roller at the initial installation of the trunnion assembly. There is a very slight angularity set on it due to setting a slight thrust on the trunnion assembly itself.
