Derivation and validation of a coal mill model for control
A simplified design schematic of a so-called roll mill is presented in Fig. 2. Raw coal is transported on a conveyor belt and dropped into the mill where it falls onto a grinding table and is crushed by rollers. Primary air blown from the bottom of the mill picks up fine coal particles and transports them into the classifier section.
