Kiln Shell Ovality - Tyre Migration

Kiln shell ovality and tyre migration are key indicators of a kiln’s mechanical condition. Ovality—the slight flattening of the kiln shell under the tyres—creates stresses on the shell and lining, while tyre migration measures the relative movement between shell and tyres. Monitoring these parameters allows early detection of deviations and implementation of corrective measures, such as shimming, to maintain alignment, extend the service life of kiln components, and prevent unplanned downtime.
