Remember that the bigger the mill, the power it will take to operate it, and even a slight increase in the size of the internal grinder can make a hand powered mill impossible to use. That’s why you have to think about how you will adjust the grain mill to run on other power sources.
Sep 13, 2010 Grinding time is related to media diameter and agitator speed via T = KD 2 N 1 2. where T is the grinding time to reach a certain median particle size, K is a constant that depends upon the material being processed, the type of media and the particular mill being used, D is the diameter of the media, and N is the shaft rpm. This equation shows that total grinding time is directly.
