The speed at which the ball mill jar rotates is responsible for maintaining the slope of the cascading media pile which is known in the industry as the "angle of break." This angle can be between 40 to 65 degrees as measured from the horizontal. If the angle is too shallow the media will not cascade much from one end to the other.
