The greatest potential for fine grinding to improve feed efficiency will be for finishing pigs, nonetheless fine grinding or rolling will improve feed efficiency regardless of age. This improved feed efficiency appears to be a result of improved nutrient digestibility. Average daily gain does not seem to be effected by reduced particle size.

Condition of screens and rollers will be critical in grinding efficiency and maintaining optimum particle size. Screens and hammers need to be checked at least monthly for wear and replaced if there are holes in the screen or if the holes become funnel-shaped. Hammers can also be reversed or replaced if they become worn.
Ball Mills - Mineral Processing & Metallurgy
In most cases it is desirable to operate the grinding mill in closed circuit with a screen or classifier as higher efficiency and capacity are obtained. Often a mill using steel rods as the grinding medium is recommended, where the product must have the minimum amount of fines (rods give a more nearly uniform product).
