Optimization of a fully air-swept dry grinding cement raw
Air swept ball mill model proposed by Austin et al. (1975) was validated by Apling and Ergin (1994) using the industrial scale data from a cement grinding circuit. In this study, production capacity of a fully air-swept dry grinding raw meal ball mill circuit was evaluated by modelling the mill using the perfect mixing modelling approach ( Whiten, 1972 ).
