When is on-site turning or grinding of kiln tyres and support rollers appropriate?
When tyre or roller surfaces show steps, grooves, taper or uneven wear while the base metal is sound and there is dimensional allowance, portable turning or grinding can restore the profile without removal, with the kiln running or briefly stopped. Deeply worn or spalled areas are usually built up by deposition first and then machined.

Before on-site machining, confirm there are no cracks, that the finished size stays within limits, how kiln speed and safety isolation are managed during the work, and whether the rollers need re-adjustment afterwards.
Turning alone, without correcting the roller positions that caused the wear, lets the surface wear unevenly again, so it is usually combined with a kiln survey and adjustment.
