Size reduction and size separation. definition, objectives of size reduction and size separation, factors affecting size reduction, laws governing energy and power requirements of mills including ball mill, hammer mill, fluid energy mill etc., sieve analysis, standards of sieves, size separation equipment shaking and vibrating screens, gyratory screens, cyclone separator, air Jul 05, 2020 the balls which could be of different diameter occupy 30 – 50 of the mill volume and its size depends on the feed and mill size. the large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. ball mills grind material by impact and attrition.The aim of the work is to investigate the breakage rate function for the size reduction of groundnut shell using ball mill. materials and method at first stage, the experiment was carried out with ground nut shell whose average size is about 3.2 mm weighing about 100 g is fed and operated at different time 10, 15 and 20 min, ball loading Using a mill or milling media, precision mills can be used for particle reduction, in order to produce fine powders. the pharmaceutical industry has been investigating the potential creation of better medications by using ball mills to significantly reduce the size of drug particles.Jun 19, 2015 the basic parameters used in ball mill design power calculations, rod mill or any tumbling mill sizing are material to be ground, characteristics, bond work index, bulk density, specific density, desired mill tonnage capacity dtph, operating solids or pulp density, feed size as f80 and maximum ‘chunk size’, product size as p80 and maximum and finally the type of circuit openclosed
