New method for measuring and analyzing the deformability and eccentricity of the ferrule kilns

Abstract

In the industrial sector, particularly in the cement industry, the key aspect of the production process is the production of clinker through the use of a rotary kiln. Due to the large volume and high temperature involved, these complex structures are subjected to stress and deformation during operation. Therefore, it is crucial to conduct regular control measurements to verify the compliance of the basic geometric parameters. In this article, we examine the literature on various control techniques, with a particular focus on the misalignment of the rotating axis of the ferrule. To measure the rotating axis and ovality of the rotary kiln cylinder, a new data processing method was developed and subsequently implemented. This method was experimentally demonstrated by creating a prototype to validate it, and the results obtained by the prototype were then compared to those obtained by the coordinate measuring machine. 
The results indicate that the proposed method is effective for determining the real axis of the rotary kiln (eccentricity) and the ovality of the shell structure. With this purpose, the article proposes a new solution for processing spatial data using a mathematical method based on the geometric parameters of the shell structure. This study can be used to develop tools for controlling rotary kilns, particularly in the data collection process.
