Summary of the Concentrating Process in Mill No 3 Introduction , Ball Mill Size Copper ,At Britannia the copper ore contained just over 1% copper (though in the early years it was around , chemical bonds and separating the elemental copper from the other mineral , the ball mills were about the size and weight of a shotput ball Characterization of Dispersion Strengthened Copper
The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel. The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones. The cyclones send correctsize material on to flotation and direct oversize material back to the ball mill for further grinding.
grinding quartz and copper ore in a laboratory ball mill, there has been defined a general form The optimal ball diameter in a mill 333 The grinding efficiency of the narrow particle size fractions with ball charge of ball charge of various sizes. Table 1. Characteristics of ball charge and sample mass of quartz and copper ore
Calculate and Select Ball Mill Ball Size for Optimum Grinding
In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize just in case. Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.
