The length of the mill is approximately equal to its diameter. Principle of Ball Mill : Ball Mill Diagram. • The balls occupy about 30 to 50 percent of the volume of the mill. The diameter of ball used is/lies in between 12 mm and 125 mm. The optimum diameter is approximately proportional to the square root of the size of the feed.

In toss juggling, a cascade is the simplest juggling pattern achievable with an odd number of props. The simplest juggling pattern is the threeball cascade, This is therefore the first pattern that most jugglers, although the shower requires more speed and precision, "some people find that the movement comes naturally to them," and it may be the pattern learned first. "

Definition of cascading. Movement of crop load in a ball mill rotating at such a speed that the balls breaking free at the top of the rising load roll quietly down to the toe of the charge. With increased peripheral speed, motion changes to turbulent cataracting and, still faster, to avalanching when the upper layer of crushing bodies breaks ...
