A ball mill is a grinder which is used to grind, blend and mix materials like chemicals, ores, pyrotechnics, paints, mineral dressing process, paint and ceramic raw materials. Its working principle is impact and attrition. Ball milling have proved to be effective in increasing solidstate chemical reactivity and production of amorphous materials.

Intermediate stops during the ball milling produced a finer aluminum flake powder than nonstop milling for up to 25 h due to cooling of the vial. A larger amount of stearic acid reduces friction between the foil or the balls and vial wall, thus give less milling efficiency, 3 wt.% of stearic acid as additive being verified as the optimum content.

The pigment particles are conventionally manufactured by wet or dry milling in ball mills from melt atomized metal powder, which only results in flat particle geometries [4]. Depending on the particle size, aluminum powder is pyrophorous [5,6], which is why aluminum pigments are usually milled in wet conditions [3].

Contact modeling. The most critical ingredient in the model of a ball mill is the contact law. Contact models belong either to the (i) discrete or (ii) continuous approach [20].While (i) is based on momentum balances, in (ii) a forcedisplacement law is added to the equation of motion, as a combination of a spring in parallel with a damper, causing energy dissipation, plus a friction ...
