    The breakage equation for roller milling allows prediction of the output particle size distribution from the feed particle size distribution in terms of a breakage function. Breakage functions were determined for First Break milling of hard and soft wheats under four roll dispositions Sharp-to-Sharp (S-S) Sharp-to-Dull (S-D) Dull-to-Sharp (D-S) and Dull-to-Dull (D-D).
