The reader is referred to Nageswararao et al. (2004) for more detail about the modified Whitenmodel. Software developmentUser functions have been defined as macros by VBA which is an integrated part of Excel (Ivens, 2000). The authors utilized this powerful feature of Excel to imple-mentmathematical modelofball mills

Jan 01, 2016· Simplifying the resulting equation themathematical model for ball mills may be written as (11.36) P = D • R − 1 • (D • R − 1 + I − A) − 1 • F. This perfect mixing model has been successfully used to simulate ball mill and rod mill operations. It can be used for steady state and dynamic simulations of milling processes
