the history of the xstrata technology isamill
According to Xstrata Technology, its IsaMill horizontal grinding mill has gained ground in the tertiary grind and the regrind markets. Originally developed for fine grinding down to 7 µm for lead/zinc ores, Xstrata Technology says the IsaMill has also established itself in coarser applications for a variety of ore types that include copper
A more sustainable approach to assessing comminution ...
The reason regrind ball mill operation has a higher indirect energy than the IsaMill operation is that it carries a penalty for using steel as grinding media. Overall, there was almost a 15% decrease in the direct energy consumption when the IsaMill was substituted for the regrind ball mill.

Mill (grinding) - Wikipedia
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
