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).

Selection function ball mill. Batch Grinding in Laboratory Ball Mills Selection Function The principle was tested on the planetary ball mill and the horizontal laboratory ball mill and according to the results obtained it can be concluded that the proposed methodology can be useful for the evaluation of the selection function during batch

Investigations were carried out in a laboratory ball mill having the size of DxL = 160x200 mm with a ribbed inside surface of the drum. The mill ball loading was 40% by volume, the rotation rate was equal to 85% of the critical speed. Balls were made from steel: S4146, extra high quality, having hardness 62 ± 2 HRC according to Rockwell.

Optimum choice of the make-up ball sizes for maximum throughput in tumbling ball mills. Various formulae have been proposed for the selection of the ball size,. and a set of scale-up criteria has been developed for scaling the parameters of the model to predict the full-scale ball-mill performance .

Please find below two calculators for sizing mills using the Bond and Rowland methods: Ball mill sizing: Calculator for ball mill(s) in a single stage circuit. Rod ball mill sizing: Calculator for rod mill(s) as first stage of the circuit and ball mill(s) as second stage of the circuit.

The ball mill can grind various ores and other materials either wet or dry. There are two kinds of ball mill, grate type and overfall type due to different ways of discharging material. Many types of grinding media are suitable for use in a ball mill, each material having its own specific properties and advantages.
