Jul 04, 2013 Operation aim of ball mill grinding process is to control grinding particle size and circulation load to ball mill into their objective limits respectively, while guaranteeing producing safely and stably. The grinding process is essentially a multi-input multi-output system (MIMO) with large inertia, strong coupling and uncertainty characteristics.

Ball mill grinding circuit is essentially a multi-input–multi-output (MIMO) system with strong coupling among process variables.

Jan 01, 1991 During these step changes the feed rate to the circuit was 136 kg/h, the circulating load 545 kg/h, the sump water rate 900 kg/h and the product size 70% passing 44 pm. Optimal control of a ball mill grinding circuit II 873 Feedback control The first task in this type of control application is the pairing of controlled and manipulated variables.

KIMA uses the optimal filling of the mill as the main control parameter. This allows the grinding process to become very stable, which allows unexpected disturbances to be accommodated more easily.
