see more details of corn flour obtained by using mm (8/64) retention screen in the hammer mill, while the starch content of the original corn flour was %. It is expected that at some threshold retention screen size, the fiber separation using the Elusieve process would be deteriorated.
#0183;#32;Two aspects of mechanical preprocessing are considered: improved size reduction via optimization of hammer mill configuration and the effect of screen selection on particle size. In order to evaluate improvements to the size reduction process, hammer mill grinding tests were conducted using a smallscale commercial grinder with a nominal power rating of 85 hp ( kW).
As the retention screen size increased, fiber separation improved, and the difference in starch content between enhanced flour and original flour increased. The highest starch content of % was in the enhanced flour from Elusieve processing of corn flour obtained by using mm (8/64) retention screen in the hammer mill, while the starch content of the original corn flour was %.
The objective of this study was to understand the effect of retention screen size in the hammer mill on fiber separation from corn flour using the Elusieve process. Four different retention screen opening sizes were studied; mm (/64), mm (5/64), mm (7/64) and mm (8/64).

Hammer mills screens are used inside a hammer mill to seperate particle sizes. Particle of small enough diameter that has been sucessfully grinded by the hammer mill passes through the screen and leaves the hammer mill with the aid of th pneumatic system.
Increasing hammer tip speed increased (linear, P lt; ) AoR. Increasing screen hole diameter decreased (linear, P lt; ) AoR. In summary, the particle size range for a specified hammermill screen size can be adjusted through manipulation of the hammer tip speed, which is made possible using motor variable frequency drives.

beater mill equipped with five screens (, 2, 3, 4, and 5 mm). Particle size had an effect on ethanol yield and on soluble solids concentration in thin stillage. The highest ethanol yield of mL/100 mL of beer was Basic processes for making ethanol
#0183;#32;Highlights Fiber separation increases starch and decreases fiber contents of corn flour. Separation has value in animal feeding and in ethanol production. Studied effect of retention screen size in hammer mill on fiber separation. Ground corn flour was sieved into size fractions, which were air classified. As the retention screen size increased, fiber separation improved.
A hammer mill is an impact mill commonly used in pharmaceutical manufacturing for reducing particle size for a variety of drugs. Commercial grade ammonium sulfate was milled as a model powder. This salt was sieved to obtain particle size fractions with average diameters of,, and mm which were used as feed particles.
hammer 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 mm to mm has resulted in linear reduction in dgw and was associated with reduction in sgw (Wondra et al.,
