Torsional Analysis and Stress Consideration of Gearing and Transmission as Related to Mills in a Cement Plant

At an early stage in the planning of a new production facility or expansion of an existing one, a cement producer must decide upon the unit size of the grinding equipment. The type of drives for the mills must also be selected. These selections are most often based upon economics, considering both the initial investment and the cost of operation. Regardless of the type of drive selected, it is of the utmost importance that the components are well matched to perform faultlessly as a unit. The strength factors in the transmission are dealt with here, as well as an analysis of the contributing loads. How the magnitude of the loads can be determined by analytical methods and by measurements will also be described.
