Grinding in Ball Mills: Modeling and Process Control
In industrial applications, the inner surface of the mill is lined with mill liners protecting the steel body of the mill and incorporating mill lifters which help to raise the content of the mill to greater heights before it drops and cascades down [36]. There are three types of grinding media that are commonly used in ball mills:

Energy Use of Fine Grinding in Mineral Processing
Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of …

Model based supervisory control of a ball mill grinding circuit
The grinding circuit ( Fig. 1) used for the present study is part of a copper concentrator plant. The system consists of a ball mill, hydrocyclones, pulp sump and associated pumps and solids feeding conveyors. The feed, copper ore (from primary crusher, size 3 in) is fed into the ball mill by vibratory conveyors.

On the contrary, metallic objects such as steel nails or iron screws can damage the grinding tools which can lead to a considerable deterioration of the mill's performance. Therefore, it is necessary to sepa-rate the metal components before grinding (e.g. with mag-netic forces).
