the grain comminution by ball impact, as well as on the basis of the experiment carried out on grinding quartz and copper ore in a laboratory ball mill, there has been defined a general form of the equation for determining: the optimal ball diameter depending on the grain size being
In batch grinding, and to a much lesser extent in closed-circuit grinding, the weight (not surface) of unfinished feed in the mill drops off rapidly as the time of grind continues. To learn if a greater mill output could be obtained than in any of the previous tests, an experiment was designed in which the period of grind was one minute.
