• Effects of mill type and particle size uniformity on

    The effects of particle size uniformity and mill type used to grind corn were determined in three experiments. In Exp. 1 120 pigs (47.8 kg initial BW) were used. Treatments were 1) a 40 60 blend of coarsely rolled (in a roller mill) and finely ground (in a hammermill) corn with a large standard deviation (sgw) of particle size (sgw of 2.7) 2

    In this article the effect of grinding media size distribution and feed material particle size distribution (PSD) on the product fineness requirements were investigated. A model free approach called the Attainable Region method was then applied in order to optimize the product size fineness in terms of the feed size and ball mix.
