    The Albion Process For Copper Applications Core

    2 Ultrafine Grinding and the IsaMill Technology Ultrafine grinding requires a different milling action than found in a conventional ball mill, due to the fine nature of the grinding media required. In most ultrafine grinding mills, an impeller is used to impart momentum to the media charge.

    (1999) highlight that tumbling mills are ultimately limited in terms of the energy they can transmit to the media, what could explain the trend towards stirred mills for fine (15-40 m) and ultrafine grinding (bellow 15 m). Figure 2 illustrates the interior of the vertical mill used at Sossego.
