This work aims to design a simple horizontal ball mill. Calcium carbonate material from limestone and eggshells powder was ground using the developed ball mill. The ball milling design significantly depends on the size of mill jar, required particle size distribution of powder and grinding media (balls) [13], [14], [15].

The effects of major processing parameters of attritor mills on ball milling efficiency (i.e., minimum energy consumption with maximum milling progress) are investigated using discrete element modeling (DEM).The major processing parameters investigated include the size of balls, ball volume fraction inside the canister, ball milling The aim of this work was to optimize the ball mill based refining process of chocolate, in terms of refining time and energy consumption. Experiments were planned following a central composite design (CCD), considering refining time (rt) and agitator shaft speed (as) as factors.The experimental variables measured were chosen from the main Optimization of processing parameters of a ball mill refiner

The ball mill modelling scheme using an ore- specific breakage distribution function in a multi-segment ball mill model has provided an adequate representation of industrial ball mill performance. Fur- ther work to extend this technique to ball mills less than 3.2 m in diameter and to mills operating at different process conditions is in progress.The model has been proposed in its complete form more than a decade ago [23], having demonstrated to be capable of describing non-first order breakage rates of coarse particles in batch mills [18] and also having been able to respond sensibly to various design and operating variables, including mill diameter, ball size, mill speed, mill fillingMechanistic modeling and simulation of grinding iron
