Difference between cement vertical mill and ball mill

Difference Between Cement Vertical Mill and Ball Mill Design Structure. Ball mills are divided into various types due to different specifications, discharge and transmission methods, but their main structures are generally the same. It is mainly composed of a cylindrical barrel, a liner, a silo plate (only for a multi-bin mill), a main The vertical roller mill (VRM), including powder separation and crushing sub-systems, is used extensively for intermediate crushing of minerals in several industries such as cement, electric power, and chemical. Compression crushing is also the main crushing mechanism in the VRM, but there is also shear force between grinding roller Analysis of vertical roller mill performance with
