    Jul 26 2021 The ratio of the diameter and length of the ball mill cylinder is relatively small usually equal to 1.0 or slightly greater than 1.0. 02 Grinding Media. Rod mills usually use steel rods with a length greater than 500mm as grinding media while ball mills use steel balls with a diameter of less than 100mm as grinding media.

  • Process Control of Ball Mill Based on MPCDO

    Process Control of Ball Mill Based on MPCDO

    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.
