To carry out the same fi nal grind, a vertical stirred mill with Millpebs will consume at least 60 per cent less energy than a ball

  • Ball Charge and Grinding Efficiency Grinding

    The volume of grinding media in a mill is directly related to grinding efficiency. The higher the volume of grinding media the more effective the grind. Balls must be added to maintain the media load and mill power draw. The power draw increases as balls are added and decreases as media wears down: add balls.

  • Effect of ball and feed particle size distribution on the

    Jun 01, 2018· Khumalo et al., 2006 postulated that generally larger sized grinding media would break larger particles quicker but a finer product would be obtained by use of smaller balls. However, use of smaller grinding media is believed to support abrasion and attrition (Katubilwa et al., 2011) which are energy inefficient breakage mechanisms .

  • The hardness of grinding media ball how to choose balls
