  same for a batch test, the standard Bond locked cycle test, or a steady state continuous mill with a real mill residence time distribution. Secondly, the method is purely empirical. Another disadvantage is the neglect of several other important factors such as the influence of lifters, percentage volume filling, ball size distribution,...
  Moreover, the mechanical grinding technique deals with a ball mill by which the powders in the mill pots can be ground into ultra-fine particles. Regardless of the technique used, most of these prior-art techniques suffer from a severe drawback: extremely low production rates. It is not unusual to find a production rate of...
