I also think that the grinding process is very important. The reasons are 1) the generation of powder in the feed 2) the decrease in moisture in the grain 3) the particle size preference of animals.-For pellet feed, a 2.4 mm screen for corn and a 2 mm screen for wheat should be selected and the other stripping grain 3.2 mm and hull grain 4 mm.

In conclusion, reducing mean PS of corn with a roller mill increased digestibility of energy and nutrients; in contrast, there was little to no effect using a hammermill. It is possible that differences in PS distribution, SD, chemical composition, and the shape of the particles resulting from the grinding process explain these differences.

The grinding process is affected by three basic variables: the type of hammers, the rotor speed, and the size and shape of the screen opening. There are two types of hammers: the "stirrup," recommended where a fine particle size is desired; and the "bar," which generates a coarser grind with a minimum of fines.

Typically, rotor speeds of 3,000–7,200 rpm are used with flat hammers for fine grinding, and speeds of 1,000–3,000 rpm are used with sharp-bladed hammers for coarse grinding. 1 The solid material is fed by gravity into the milling chamber and is crushed or shattered by repeated hammer impacts, collisions with the walls of the chamber, as ...
