The parameters of mill load (ML) not only represent the load of the ball mill, but also determine the grinding production ratio (GPR) of the grinding process. On-line monitoring and recognition of milling conditions has significant effect on the operating efficiency, product quality, and energy and grinding media consumption for the milling circuit. This paper presents a hybrid grinding media charging system incorporating an intelligent agent and design of the hoppers used in the charging system. A control logix program is designed to determine the precise quantities of grinding media to be charged in an incremental manner such that shock loading is avoided. The intelligent agent created in Java Agent Development framework (JADE) is monitors the power drawn by the ball mill and the mill load such that proper charging conditions are established. High quality of the regulation process is achieved through utilization of the control logix and the intelligent agent.
