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

Mill Selection The first step in mill design is to determine the power needed to produce the desired grind in the chosen ore The most used equation, for this purpose, is the empirical Bond equation (Bond, 1960, 1961; Rowland and Kjos, 1978)

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 …

The ball mill in closed circuit with hydrocyclones is an industry standard, and well known methodologies exist for equipment sizing, selection and design; however, the potential to improve the capacity of ball mill circuits by replacing cyclones with screens has been recognised for many years and

The type of mill also can affect the selection of grinding media Ball Mills use very large media while Attritors employ media ranging in size from 1/8” to 1” Horizontal mills require much smaller media, as small as 005 mm to 2 mm

The ball size is one of the critical factors for determining the mill performance of ball mills It is well known that larger balls are needed for the effective breakage of large-size particles, whereas smaller balls are more effective for the breakage of fine particles Therefore, it is a common practice in industry to use a mixture of balls rather than balls of a single-size to ensure the
