Between Hot Kiln Surveys: Our Article in Global Cement Magazine
We are proud to announce that our article "Between Hot Kiln Surveys", written by Alpay Zeren, has been published in the September 2026 issue of Global Cement Magazine (pages 28–30).

What the article is about
A hot kiln alignment is normally performed once every 1–2 years. The article looks at what happens in between: a kiln keeps changing because of wear, operating temperature and process conditions, so a small mechanical change can go unnoticed until the next scheduled survey. Routine measurements performed by the plant's own maintenance team can close that gap.
The article covers:
- Tyre migration — why it should be checked regularly, and why both increasing and decreasing trends deserve attention
- Why migration values must be recorded alongside shell and tyre temperatures, so mechanical changes can be separated from thermal effects
- Tyre axial run-out and roller shaft deflection — how repeated measurements at the same location reveal changing support conditions
- A practical inspection schedule — which parameters plant staff can check daily, weekly and monthly, and which belong to specialist surveys
- A case study from a European cement plant, where routine MMD measurements caught a rising tyre axial run-out trend (from about 1.2 mm to 2.6 mm over 12 weeks) and led to corrective work at the next planned stoppage
The role of the MMD Kiln Inspection Tool
The article also describes how our portable MMD Kiln Inspection Tool supports this routine measurement workflow: tyre migration, tyre diameter, tyre axial run-out, roller shaft deflection and girth gear run-out measurements with the same device and the same repeatable procedure each time. A routine MMD check takes approximately ten minutes.
The purpose of routine measurements is not to replace the specialist hot kiln alignment — it is to identify changes earlier and to decide if and when a more detailed inspection is needed.
