Rotary Kiln Ovality Checking

Ozek Makina Rotary Kiln Services Frequently Asked

In hot kiln alignment services we give a packservice including all necessary measurements analysis and suggestions about your rotary kiln We measure ovality crank shell deformation eccentricity informations about shell and connect all information in a sophisticated wireframe data to understand the kilns behaviour.

Measurement Tools For The Cement Industry

The Ovality Sensor is a measurement tool for rotary kilns which measures the changes of the roundness curvature in the kiln shell during operation This elastic deformation is called Ovality and is primarily present in the area of a kiln tire.


against such breakdown is checking and adjusting the alignment of the kilns at least once a year There are several other breakdown issues associated with the kiln the most important of which is deflection of the kiln from the original position due to ovality of the kiln the kiln shell becomes oval in shape during the course of its operation.

The parameter expressing shell deformation at a certain point is the kiln shell ovality co Definition of co co2 a b with 2a and 2b as the main axis of an ellipse Investigations have shown that generally a maximum relative ovality co of 03 is allowed This ovality may be subdivided into two amounts a Ovality of the riding ring 3 cm.
