Further DetailsSep 01 2013 · For the feed size of 90 passing 189 mm Fig 6 a the maximum capacity was obtained with 100 of a makeup ball size of 508 mm As the feed size is reduced to 134 mm a 6238 mix of 508 mm and 254 mm balls was found to be the optimum mix
Further DetailsA ball mill is a type of grinder used to grind blend and sometimes for mixing of materials for use in mineral dressing processes paints pyrotechnics ceramics and selective laser works on the principle of impact and attrition size reduction is done by impact as the balls drop from near the top of the shell A ball mill consists of a hollow cylindrical shell rotati
Further Detailsand with the decreased grain size the necessary ball size also decreases Olejnik 2010 2011 For each grain size there is an optimal ball size Trumic et al 2007 The bigger ball in relation to the optimal one will have an excess energy and consequently the smaller ball mill has less energy necessary for grinding In both
Further DetailsOptimization of mill performance by using online ball and pulp measurements by B Clermont and B de Haas Synopsis Ball mills are usually the largest consumers of energy within a mineral concentrator Comminution is responsible for 50 of the total mineral processing cost In today’s global markets expanding mining groups are trying
Further DetailsThe design of a ball mill can vary significantly depending on the size the equipment used to load the starting material feeders and the system for discharging the output product The size of a mill is usually characterized by the ratio “length to diameter” and this ratio most frequently varies from 05 to 35 The
Further DetailsThe types of mills are distinguished by their working principles by pressure impact hammer or shear Mills could be equipped with a screen for grain size control and separation The FAM product range includes impact mills roller mills hammer mills ball mills and rod mills
