Milling operations in various production processes are among the most important factors in determining the quality, stability, and consumption of energy. Optimizing and stabilizing the milling process is a nonlinear multivariable control problem. In specific processes that deal with natural materials (, cement, pulp and paper, beverage brewery and water/wastewater treatment industries).

Cement milling is the process of grinding together cement clinker, gypsum and other additives to produce a fine grey powder. The resulting material, called "cement meal", is then heated in a rotary kiln to around 2,000°F to produce the finished product known as Portland cement, which can be used for many different construction purposes.
