Design Of Shaft In Ball Mill A Study Of Comminution In

  • MEI Blog: Comminution '16 conference diary - Barry A. Wills

    Apr 25, 2016 · The particle sizes that can be fed to a ball mill depend on the ball size distribution of the charge and more specifically, the diameter of the make-up ball. This is also a function of the tenacity of the particles as this controls the size at which the selection function is maximum for a given ball .
