Read Morehammer mill screen size on dgw has been reported for different hammer milled grains such as corn (Wondra et al., 1995,a) and in sorghum (Owsley, et al., 1994). In addition, reduction of hammer mill screen size from 9.6 mm to 1.2 mm has resulted in linear reduction in dgw and was associated with reduction in sgw (Wondra et al.,
Read MoreThe LST 60° CONIC HOLES screen surface is similar to that of a “cheese grater”.This unique type of raised and inclined conic hole creates a cutting rasp that reduces the milled product in smaller particle sizes. Therefore, our screens provide hammer mills with a more aggressive pulverization action, compared with that of a conventional circular hole screen type.
