Stably controlling the pre-grinding process is paramount important for improving the operational efficiency and significantly reducing production costs in cement plants. Recognizing the complexity in both structure and operation of the pre-grinding process, this paper proposed a fuzzy and model predictive control system to stabilize and optimize the pre-grinding process.

Abstract This paper presents the design and application of a multiple-input–multiple-output fractional order proportional-integral (MIMO FOPI) controller to a grinding mill circuit. The MIMO FOPI controller parameters are tuned using an off-line optimization process based on Particle Swarm Optimization (PSO). Its performance is compared to a single-input–single-output fractional order ...
Model Predictive Control for SAG and Ball Mill Control Real-time optimization based on a model predictive controller is considered a better approach to SAG and ball mill control. inputs, and to solve for the best set of control actions on a fixed cycle – typically less than one minute.
2. Cement Grinding Mill The schematic diagram of the finish milling circuit is shown in Figure 1. The feed to the finish milling are the clinkers (product from the rotary kiln of cement plant) that have varying grindability. The clinkers along with gypsum and fly ash enter the ball mill. The input material are grinded in the ball mill by the
