Dec 17, 2020 Dry batch milling kinetics tests were done in a lab-scale mill, 17.8 cm in diameter and 4.5 L in capacity, on a 600 cm 3 representative volume of each Penouta mine sample. The mill charge consisted of 5.0 kg of steel balls, of 19.0 mm, 22.0 mm and 31.0 mm monosizes. Fill fraction was calculated from Equation (6).
This is rudimentary ball mill in Busia, Uganda. People tend to use very big balls inside for the reason that they do not use primary crushing properly. Thus big ball helps that rocks get crushed. No liners are used and such rudimentary ball mills are broken each in a while, they don't last in operation longer than just few months when they need to get repaired.

A major ball mill manufacturer presents a persuasive case for choosing this proven — and improved — design over other types. Over many years of use, shell-supported ball mills similar to those pictured above have proven their efficiency and reliability, and a large number of mining projects would not have been viable without them.
Laboratory-scale batch grinding tests were performed on 2 sieve size fractions of the almost pure hematite mined at the Carajas mine of CVRD Brasil. Good first-order kinetics of grinding were obtained, both for dry grinding and for grinding with water, using the Bond test levels of ball load and powder load.
