Nov 01, 2002 in terms of this concept, the energy efficiency of the tumbling mill is as low as 1, or less. for example, lowrison 1974 reported that for a ball mill, the theoretical energy for size reduction the free energy of the new surface produced during grinding is 0.6 of the total energy supplied to the mill ball mill.
Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. as the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. with this motion, the particles in between the media and chamber walls are reduced in size by ball mill.
