Therefore, a roller mill may be a better alternative to a hammermill for swine feed processing [1]. However, roller mills require more vigilance to maintain a gap width that will produce the targeted particle size. Roll gap width will change as rolls wear and grain qualities change. Hammermills will require less monitoring by comparison.
