The material is thrown off the roll in all di-- rections by centrifugal action. For example in present day practice an average speed for 15 diameter rollers in a triple roller mill is respectively 20, 45 and 120 revolutions per minute, and if the periphery speed of the top speed roller is increased to a high speed, centrifugal action of the material brings about the throwing off above referred to and a practical working of the mill is destroyed.

My grinding mill has length and diameter of 4.57 m. the maximum size of the balls selected is 77 mm, as there are two or three kinds of ball sizes used how to select the second ball size. are there any formula or equation that i can calculate the ball size.
Ball size is usually dictated by the size of the feed material you are grinding, and only minimally dependent on the dimensions of the grinding mills.
There are two equations commonly used to estimate the ball size, first is Azzaroni039s equation and second is Bond039s equation. Both predict a single size of ball to recharge an operating mill there are different equations for the range of ball sizes for the first charge of a new mill.
