Disturbance observer based multi-variable control of ball
Ball mill grinding circuits are essentially multi-variable systems characterized with couplings, time-varying parameters and time delays. The control schemes in previous literatures, including detuned multi-loop PID control, model predictive control (MPC), robust control, adaptive control, and so on, demonstrate limited abilities in control ball mill grinding process in the presence of strong

Application of model predictive control in Ball mill grinding
Ball mill grinding is a multi-input multi output (MIMO) system. Based on a four input- four output model, the unconstrained model predictive controller is designed. In this paper, a model predictive controller (MPC) based on CARIMA model is used to control the process. The model of the ball mill circuit is described.

How to Control the Ball Mill Noise?
The ball mill can Reduce the ball mill noise below the allowable standard. (3) The ball mill uses a rubber liner instead of a manganese steel liner. The noise level can be reduced by 9dB (A), and the frequency spectrum characteristics of the ball mill are also changed from high frequency to low frequency. Ball mill design soundproof room.
