Fine Grinding Technology for Mines and Concentrating

The IsaMill (high capacity horizontal stirred mill) is referred to as an enabling technology. Through significantly lowering the cost of fine grinding, many locations that had high grade but fine grained ore became economical. Stirred mill technology energy efficiency is extremely dependent upon several variables including grinding media selection.
