Mafezzoni (1996) described this developed model as more of a knowledgebased model than a control model. Control of coal mills up to a certain extent has been developed (Fan and Rees, 1994). A team from ABB designed a coal mill model for monitoring and control based on Fan and Rees principle using 3 particle size (Mercangoez et. al. 2011).
