The grinding process of the ball mill is an essential operation in metallurgical concentration plants. Generally, the model of the process is established as a multivariable system characterized with strong coupling and time delay. In previous research, a twoinputtwooutput model was applied to describe the system, in which some key indicators of the process were ignored. To this end, a three ...
