Is particle size important for swine diets
Low moisture grain will shatter more creating more fines than normal moisture content of 1012 percent Increasing the flow rate of grain through the hammer mill will tend to increase particle size but it may result in more variation of particle size Roller mills have the advantage of creating a more uniform particle size than a hammer mill.

Hammermills versus roller mills
In a hammermill the screen hole diameter controls the maximum finished particle size of any ground product When using roller mills there is no screen being used and unless the product is sifted and the coarse fraction reprocessed the resultant particle size is purely reliant on the miller’s skill in setting the roller mill effectively.
