A Review of the Grinding Media in Ball Mills for Mineral Processing
The ball mill is a rotating cylindrical vessel with grinding media inside, which is responsible for breaking the ore particles Grinding media play an important role in the comminution of mineral ores in these millsA ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering It 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 rotating about its axis The axiBall mill

In relation to this issue, Shi (2009) demonstrated that the application of vertical stirred mills presents the energy saving around 30% when compared to tumbling ball mills used for coarse grinding By applying various methodologies, other researches confirmed the obtained results and reinforced this better energy efficiency behavior for Ball mills are commonly used in the manufacture of Portland cement and finer grinding stages of mineral processing Industrial ball mills can be as large as 85 m (28 ft) in diameter with a 22 MW motor, [6] drawing approximately 00011% of the total world's power (see List of countries by electricity consumption )Mill (grinding)
Model based supervisory control of a ball mill grinding circuit
The grinding circuit (Fig 1) used for the present study is part of a copper concentrator plant The system consists of a ball mill, hydrocyclones, pulp sump and associated pumps and solids feeding conveyors The feed, copper ore (from primary crusher, size 3 in) is fed into the ball mill by vibratory conveyorsThe optimization of processing plants is one of the main concerns in the mining industry, since the comminution stage, a fundamental operation, accounts for up to 70% of total energy consumption The aim of this study was to determine the effects that ball size and mill speed exert on the milling kinetics over a wide range of particle sizes Kinetics of DryBatch Grinding in a LaboratoryScale Ball Mill of
