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.

Planetary ball mills are used for the pulverization of soft, hard, brittle, and fibrous materials in dry and wet mode. Extremely high centrifugal forces result in very high pulverization energy and therefore short processing times. Planetary ball mills are ideally suited for tasks in research like mechanochemistry (mechanosynthesis, mechanical ...

The critical speed of a ball mill is the speed at which the centrifugal force is equal to the gravitational force acting on the balls. At this critical speed, the balls are held against the inner wall of the mill and do not fall to the bottom where they would be more effective at grinding the material.

Rose and Sullivan showed critical rotation speed N c, to reach the final stage,, centrifugal motion: (1) N c = 1 2π 2g D−2r where D is the inner diameter of a jar and r is the radius of balls. All throughout, they used the critical rotation speed as the constant value for given conditions of ballmill [5].
