Loading the Mill: The ball mill is loaded with the material to be ground and the grinding media (balls). The material can be fed into the mill either wet or dry. Rotating the Mill: Once loaded, the cylindrical shell starts rotating around its horizontal axis. Various mechanisms, such as gears, belts, or direct drives, can facilitate this rotation.

For example, the use of VRMs in combination with ball mills has been shown to reduce energy consumption by up to 50% compared to traditional ball mills alone. Similarly, the use of VRMs in combination with high-pressure grinding rolls (HPGRs) has been shown to improve product quality and reduce energy consumption.

sonable to replace, totally or partly, ball milling for HPGR wet grinding after filtering. This substitution makes it pos-sible to shorten the time of iron ore inside a ball mill, the ball mill output grows as a result, and a larger size product is obtained. The grain size required for pelletizing is reached in further HPGR grinding (Fig. 5).
