Abstract. Three experiments were conducted to study the effect of particle size obtained by grinding wheat and sorghum in a hammer mill (HM) or roller mill (RM) on broiler performance. Broilers were fed a mash diet or crumbles to 4 wk of age, then pellets to 7 wk of age. When fed as a mash, diets produced with RM-ground grain improved performance.

The particle size of ground feed ingredients, for example, has a direct influence on subsequent processing and handling of the feed. Finer grinding of the particle will result in a better quality pellet or extruded feed. It also increases the capacity of your pellet mill or extruder, and reduces wear on the equipment's working parts, such as ...

In case of grinding fine particles of the size of 200 nm or smaller, the selection of beads' size is quite important. Since the inter-bead space among larger beads is larger, opportunities for the particles to come into contact with the beads …
