the effect of heat in a roller mill

Effects of alkali debranning, roller mill cracking .Studies on debranning showed that optimal separation between pericarp and corn endosperm was obtained when corn was soaked in a 1.5-2% NaOH solution at 85°C for 5 min. Passing debranned corn through a smooth roller mill once or twice did not affect the product yields, but passing the corn through the roller mill three times decreased the germ yield because of a large amount of broken germ.Cement mill - WikipediaRoller mills. These have been used for many years for the less exacting raw-milling process, but recently roller mills, in combination with high-efficiency separators, have been used for cement grinding. The grinding action employs much greater stress on the material than in a ball mill.
