In the mining industry, all kinds of mills are developing towards large-scale. This paper introduces the changes of the working state of large-scale mills and their influences on the design, and discusses the reasons why the large-sized mills require more accurate and reliable analysis of mill structures, The influence factors of work stress and the design standards, the design changes and new design ideas of large-scale components such as drive system, gear structure and gearless (ring type motor) transmission, hydrodynamic bearing and trommel are introduced, and Three Dimensional Finite Element Load Analysis Model Applied to Large Ball Mill
