The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods, and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent. It is especially difficult to teach mill

Configuration of the grinding vessel. Generally, there are four grinding vessel volumes available for grinding with manual mills (10, 50, 100 and 250 cm³). Only 100 cm³ grinding vessels are used in the case of automatic mills. If smaller grinding vessels are used in larger holders, intermediate rings and spacers can be used as adapters.

In his book, Evans describes a system that allows the sequential milling of these grists, noting that "a mill, thus constructed, might grind grists in the day time, and [do] merchantwork at night." Over time, any small, older style flour mill became generally known as a gristmill (as a distinction from large factory flour mills).

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).

As mentioned earlier, pebble mills are widely used in the North American taconite iron ore operations. Since the weight of pebbles per unit volume is 35–55% of that of steel balls, and as the power input is directly proportional to the volume weight of the grinding medium, the power input and capacity of pebble mills are correspondingly lower.
