Torsional Vibration Problems and Analyses of Cement Industry Drives

Torsional vibrations in various types of drives utilized by the cement industry can have a large economic impact due to lost production when consequential component failures result in unscheduled shutdowns. Each type of drive will have a different set of torsional vibration problems that can develop under certain conditions. A general understanding of the fundamental nature and cause of various types of torsional problems provides the basis for defining and conducting design assurance analyses. Such analyses can greatly reduce the risk of developing problems. A discussion aimed at such an understanding, along with examples of problem experiences and analyses carried out on industry drives, is given.
