Jul 26, 2021 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 two-input-two-output model was applied to describe the system, in which some key indicators of the process were ignored.

Apr 01, 2002 Abstract. The design and scale-up of ball mills are important issues in the mineral processing industry. Incomplete knowledge about the mechanics of charge motion often forces researchers to rely on phenomenological modeling to formulate scale-up procedures. These models predict the behavior of large industrial-scale mills using the data obtained in small laboratory-scale mills.
