Because OEMs and repair companies apply different methods to calculate kiln misalignment, you might find it challenging to evaluate the service proposals you receive from suppliers performing their version of a hot-kiln alignment. When looking for support in kiln alignment, there are a few considerations to
evaluate:
What is included in the alignment?
An Alignment Analysis of the unit is often combined with a Mechanical Survey in order to identify, diagnose, and correct any issues before they develop into major problems. Metso Outotec Alignment Analysis contains a range of measurements using different tools to ensure all key parameters are analyzed.
How experienced are the service providers?
The use of accurate and proven procedures, performed by experienced and qualified personnel should be of paramount importance to the operator. Metso Outotec has crews with many hundreds of hours of experience on all makes and types of rotary equipment.
Is the latest technology being employed?
Proper diagnostics tools and methods should be utilized. For example, some rely on measurements of the riding ring and the associated tire slip or creep. However, given that the tire surface can be irregular due to wear and is often contaminated with lubricant and dust, basing kiln alignment on tire measurements alone is of questionable accuracy. Metso Outotec uses state-of-the-art high-frequency laser equipment to capture data with a high degree of accuracy, calculating the position of the kiln shell rotational axis at each support. Calculations include allowance for flexure, shape distortion, and eccentricity of the shell.
