Interpretive Summary:

Technical Abstract: Particle size reduction is a widely used process for cereal grains. In wheat flour milling the wheat kernel after tempering is passed through a number of rollers to break and reduce the particle size and sifted into flour and millfeed fractions. In corn dry milling the kernel after tempering is broken into large pieces by a degerminator and then sifted, aspirated and ground between a number of rollers into grits, flour, germ and meal. Miag vario mill, Allis-Chalmers roller mill, Glen Mills micro hammer/cutter mill, Buhler mill, and Alpine pin mill were used to concentrate gum from defatted Lesquerella seed meal by grinding and sifting/air classification. The best result was obtained when the defatted meal was ground at 14,000 rpm and separated by air classification.
