grinding unit efficiency

  • Unit Operations in Food Processing

    It has been found, experimentally, that for the grinding of coarse particles in which the increase in surface area per unit mass is relatively small, Kick''s Law is a reasonable approximation. For the size reduction of fine powders, on the other hand, in which large areas of new surface are being created, Rittinger''s Law fits the experimental data better.
