of the wide variation in kinds of comminution events in the ball mill and because of possible untouched feed, the ball mill product follows equation (2a) only in the finer sizes, with large deviations in the coarser sizes. In terms of the kinetics of particle formation in a ball mill. one
Similar to a Comparative Work Index, this test is an open circuit dry batch grindability test run in the standard Bond Ball Mill for a set time. It can be used at mesh sizes from 65 to 200 mesh (normally 100 mesh). The test requires calibration against the standard Bond Ball Mill .
Bond ball mill test procedure were carried out on crushed (-3.35 mm / 6 mesh) material at different screen closing sizes (300 µm, 212 µm, 150 µm, 106 µm, and 75 µm). The screening process was conducted in four sets of 12-inch diameter screens for sufficient amount of time to avoid too much materials fed into the screen at one time.

Particle size distribution influences the physical and chemical properties of solids. Therefore this criterion is of highest importance in the context of science and quality control. Only if the size distribution remains constant, a steady product quality can be guaranteed, as the following examples show:
Ball mills can be used to further break down or refine a single material, or you can place multiple materials into a ball mill jar to mix as you pulverize -- this is a very common industrial solution for mixing glazes that require the smallest of mesh sizes. Ball mills basically function like a mortar and pestle, but on a much larger scale.
