The IsaMill is a recent addition to ultrafine grinding process equipment. It was commercially commissioned in the early 90s. It is now widely used in the platinum, lead, copper, nickel and zinc industries. This process equipment was developed in an effort to help recover values from old mine dumps (Curry et al., 2010).

The IsaMill™ with its internal classifier keeps the grinding media away from the discharge. This technology enabled the fine grinding of minerals in an open circuit. Since the classifier implies a current counteracting the drag forces due to the product flow, it gets more complex to understand the axial distribution of the grinding media.
