We discuss the types of ball mill, the basic principles of the ball mill, how it works, the details of design including equations for optimum dimensions in all cases, some manufacturers for the ball mill, and estimation of the cost the ball mill 6 1 Introduction Ball mill 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 Calculate and Select Ball Mill Ball Size for Optimum For overflow ball mills, the charge should not exceed 45% of the mill volume For grate discharge mills, the charge should occupy about 50% of the mill volume Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, ie,AMIT 135: Lesson 7 Ball Mills Circuits – Mining Mill The geometry of a mill with conical ends is shown in Figure 86 The total volume inside the mill is given by Vm 4 D2 mL 1 2(Lc L) L 1 (Dt/Dm) 3 1 Dt/Dm (816) The density of the charge must account for all of the material in the mill including the media which may be steel balls in a ball mill, or large lumps of ore in anTECHNICAL NOTES 8 GRINDING R P King (1984), it was stated that, tumbling action in a ball mill can be simulated in the double impact tests such as drop weight and pendulum methods although the energy available for particle breakage can only be obtained from pendulum tests (Lynch et al, 1986)Thus these type of tests were widely used for the characterization of oreSINGLE PARTICLE IMPACT BREAKAGE
