The calculations are based on pilot plant experiments with a ball mill and 150 mm-hydrocyclones. The process conditions are presented in Fig. 4. By varying the other parameters such as hardness, primary feed rate, size distribution of the feed and water addition, mill parameters were kept constant. The control acts on the hydrocyclone, thus

By the control viewpoint, the ball mill grinding circuit should be operated as a multivariate connected system that has very strong interactions between all process variables. For example, in a very simple and integrated structure, a closed loop circuit in a wet mill has a ball mill, a sump and a spliter or divider [10, 13, 33, 39].

Ball Milling
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

How to control the ball mill noise? Ball mill is mainly used for grinding materials in the industrial production process. Due to the large volume and heavy tonnage, the noise ( strong vibration and noise ) generated is usually above 95dB(A), which is serious affects the physical and mental health of workers.

5. Abstract The Ball mill is one of the most important equipment in the world of chemical engineering. It is used in grinding materials like ores, chemicals, etc. The types of ball mills: batch ball mill and continuous ball mill with different grinding media and different design depend on the nature of the input material and the nature of the

A self-optimizing, high precision sampling fuzzy logic controller for keeping a ball mill circuit working stably and efficiently is proposed in this paper. The controller is based on fuzzy logic control strategy, and a fuzzy interpolation algorithm is presented to improve the control precision. The final output of the controller is calculated through the interpolation calculation of the
