The volume of the ball is calculated by the formula V = 4 / 3πr³ . This formula is the same in the whole world. It is as accurate as possible with respect to balls of perfect shape, but you can calculate the approximate volume of imperfect earth objects. Let your balls always stay in perfect shape.

For example, to calculate the volume of a cone with a radius of 5cm and a height of 10cm: The area within a circle = πr 2 (where π (pi) is approximately and r is the radius of the circle). In this example, area of base (circle) = πr 2 = × 5 × 5 = 2. × 10 = 785. 785 × 1/3 = 3.

The mill power is also increased by increasing the rod charge and the mill speed, while the mill power and capacity are both increased with increasing mill length. Based on these observations and working on wet overflow mills, Rowland and Kjos [2] suggested that the power draw at the pinion shaft per unit mass of rods is given by () P M M R ...

Although it was developed nearly 50 years ago, Bond's method is still useful for calculating necessary mill sizes and power consumption for ball and rod mills. This paper discusses the basic development of the Bond method, the determination of the efficiency correction factors based on mill dimensions and feed characteristics, and the application of the results to designing grinding circuits.

We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill.
