Cement milling circuits are controlled by linear quadratic strategies with the purpose of retaining the circuit stability. Generally, the controlled variables of milling circuits present discontinuities over the range of values they take during the plant operation. The design of linear quadratic control algorithms is based on linear approximations of the nonlinear …

Where semi-finish grinding is desired, the Hydraulic Roller Press can be combined with a two-stage separator system and a conventional ball mill. A dynamic separator, which maintains the desired quality of the final product is paired with a static separator that ensures effective deagglomeration and aids in drying the feed material.
