The correct sizes are often determined by trial and error, primary grinding usually requiring a graded charge of 10-5 cm diameter balls, and secondary grinding requiring 5-2 cm. Concha et al. (1988) have developed a method to calculate ball mill charge by using a grinding circuit simulator with a model of ball wear in a tumbling mill.

 — 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 …

Gross Power Draw and Specific Energy Calculator for Semi-Autogenous Grinding (SAG) and Ball Mills. Return to Mill Calculators.

 — Various operational parameters, such as mill speed, the ball charge composition, charge filling, lifter type, and lifter number, significantly impact ball milling grinding efficiency [3].

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.
