The rotary kiln is used for the pre-treatment step in the production of Portland and other types of cements. For the rotary kiln, the roller shafts are among the main parts that make up the kiln. They are considered the most important items related to safety because a roller shaft that has damage can directly cause an accident (Chapman 1985 ).

Hot Kiln Alignment - Geoservex

Measurements of rotary kiln shell deformation constitute a significant part of our extensive offer of kiln inspection. Geoservex was the pioneer in the field of these measurements, covering the scope ranging from simple measurements of distance and geometric approximation of a cross-section shape, to linear laser scanning and unique computer software development enabling the calculation of ...
