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. from top to bottom while striking nothing in between. Still

The ball mill is a tumbling mill that uses steel balls as the grinding media. The material that is to be ground fills the voids between the balls. The tumbling balls capture the particles in ball/ball or ball/liner events and load them to the point of fracture. When hard pebbles rather than steel balls are used for the grinding media, the mills are known as “pebble mills.” As mentioned

The voids (or interstitial space) within a rod load are approximately half those in a ball mill grinding load. Rods in place weigh approximately 400 pounds per cu. ft. and balls in place approximately 300 pounds per cu. ft.. Thus, quantitatively, less material can progress through the voids in the rod mill grinding media than in the ball mill, and the path of the material is more confined
