to an industrial semiautogenous (SAG) mill in Craig and MacLeod (1995, 1996), and the linear model predictive control for an industrial ball mill circuit in Chen et al. (2007). A robust nonlinear model predictive controller (RNMPC) was proposed by Coetzee et al. (2010) to control a ROM ore milling circuit. Full state feedback was assumed.

High hardness materials become very abrasive; therefore, they are not suitable for highspeed hammer mills. In a typical jet mill, grinding action is caused mainly by particleparticle collisions, so wear to the mill's internals is less of an issue.
