Apr 01, 2015 Perfect mixing model was used by Benzer 2004 in modelling of an air-swept raw meal grinding ball mill by considering the single compartment mill as three perfectly mixed tanks whereas air-sweeping through the mill was modelled by a classifier at the mill discharge. In the model, tank-1 corresponded to the mill length where lifting liners were applied whereas tank-2 and tank-3 lengths corresponded to the mill
