What It Finds
polscan® is a highly accurate optoelectronic measuring method that can measure rotary kilns quickly and precisely during operation. It allows us to reliably diagnose vertical and horizontal deviations of the rotary kiln axis, as well as the deformation, eccentricity and ovality of the kiln shell. Availability of the rotary kiln is therefore significantly higher, because damage is detected early.
| Axis deviation | Vertical and horizontal deviations of the rotary kiln axis |
| Deformation | Deformation of the kiln shell along its length |
| Eccentricity | Eccentricity of the kiln shell |
| Ovality | Ovality of the kiln shell — the driver of refractory life |
The Four Options
Our range of services comprises various options — precisely according to your needs. Assignment time and financial expenditure can be calculated in advance, for every one of them.
| Option | Scope | Includes |
| Option 1 — Kiln axis | We check the rotary kiln axis and carry out various further measurements | Vertical and horizontal axis deviation · dimensions of the tyres · dimensions of the supporting rollers |
| Option 2 — Shell deformation | We record the deformation and eccentricity of the kiln shell, including further measurements | Deformation of the kiln shell · eccentricity · axial runout of the tyres |
| Option 3 — Shell ovality | We measure the kiln shell ovality | Ovality measurement · basis for refractory life assessment |
| Option 4 — Kiln statics | Taking into account current kiln data and measured values, we carry out a calculation of the kiln statics | Various loads determined · various stresses determined · built on measured values rather than assumptions |
What You Get
The measurement is not the deliverable — the interpretation is. Four steps follow every measurement.
All measured values are stored and remain available for subsequent calculations
After completion of the measurements, documentation with informative reports is generated on-site
The documentation is discussed with the customer and handed over
A written report contains explanations of the measurement records as well as recommendations for mechanical plant optimization, as determined during the measurements
What a Result Turns Into
Optimization of preventive maintenance through precise analysis of the measurement results. In practice that means one of three things, each cross-linked on the page.
| An alignment | Adjustment of the supporting roller bearings, carried out by thyssenkrupp if requested — the direct correction of what the measurement found. Links to the rotary kiln page, roller stations section |
| A planned shell replacement | Where shell condition is the issue, the kiln statics service determines and dimensions the supports needed to counteract sagging, so the section change is statically safe and accurate. Links to kiln statics |
| A spare parts decision | Tyre and supporting roller dimensions, ovality and axial runout are exactly the inputs that turn into a stocking list and a plannable replacement instead of an emergency order. Links to Spare Parts Management |
