The Global Grinding Media Market size is projected to grow moderately in terms of value, from $6.9 billion in 2021 to X.XX billion by 2028, at a CAGR of 5%.

The larger con- tact surface of the grinding media during the collision with the wall or with the other grinding media at equal other conditions increases the effectiveness of the grinding process. If the center of gravity of the grinding media coincides with their geometric center, they wear out evenly and their life becomes longer.

Bureau of Mines research showed that galvanic interactions between grinding media and chalcopyrite influence the self-induced floatability of chalcopyrite in simulated process water. Similar results were obtained with a synthetic chalcopyrite-quartz mixture and a natural ore, and floatability was dependent on the electrochemical conditions in grinding, conditioning, and flotation stages.

autogenous grinding machines fracture of the media particles also occurs by both impact (self breakage) and attrition. The relative motion of the media is determined by the tumbling action which in turn is quite strongly influenced by the ... dynamic conditions inside the mill.
