mill mining rates

  • energy savings and technology comparison using small . CEEC

    As mentionned by McIvor (1997) and Nesset et al (2006), the media size is the most important variable affecting the mill efficiency. As explained by Jankovic (2003), the definition of fine grinding varies from one industry to another. For the mining industry, the conventional ball milling can grind to a final product of 80 per cent.
