The present work discusses a systematic approach to model grinding parameters of coal in a ball mill. A three level BoxBehnken design combined with response surface methodology using second order model was applied to the experiments done according to the model requirement. Three parameters ball charge (numbers 1020), coal content (100200 g) and the grinding time (48 min) were ...
