The ball mill is the largest single power consumer in a cement plant. In recent applications 11,500 hp and larger drives have been installed. It is essential that with such large loads all aspects of the application are subject to evaluations that reflect the best available technology and operating practices. This paper examines the factors which influence the selection process: the type of ...
