The grinding behavior in a ball mill has been studied mostly from the viewpoint of the effects of such main factors, as the velocity of revolution of the mill, the size of ball, and the packing ratio. However, there is no systematic investigation to clarify their interactions. In order to know the grinding behavior of silica sand in a ball mill, the interactions among the velocity of revolution of the mill, the size of ball, and the packing ratio are studied using the method of "the experimental designs". The most effective condition for grinding silica sand with the particle size from 53 to 5μ is 72 rpm, 31 mm, and 30% for the velocity of revolution of the mill, the ball size, and the packing ratio, respectively. On the other hand, the most effective condition for the one with the particle size smaller than 5μ is 72 rpm, 31 mm and 20%. These results are used to discuss the grinding behavior in a ball mill.
