Abstract Wheat and barley straws, corn stover and switchgrass at two moisture contents were ground using a hammer mill with three different screen sizes (3.2, 1.6 and 0.8 mm ). Energy required for grinding these materials was measured. Among the four materials, switchgrass had the highest specific energy consumption ( 27.6 kW h t 1 ), and corn stover had the least Hammer Mill Modest increase in fines compared to infeed material Effective at grinding particles greater than 1.5 mm in size Rotary Shear Did not createfines Effective at grinding particles greater than 3 mm in size Collision Mill Created the finest and roundest particles Infeed Corn stover

AFEX pretreated prairie cord grass and switchgrass with 20% moisture content at a screen size of 2 mm produced pellets having 25% and 21% higher unit density. The decrease in hammer mill screen size and the increase in moisture content and applied pressure increased the pellet unit density. was 1.812.7 g/kg for Arbequina and 0.55.4 g/kg for Koroneiki. In general, smaller hammer mill screen size and enzymes increase total phenols in the oil, with a larger dierence between control and treatment for green fruit than for the ripe fruit.

4. The 2.0-mm hammer-mill screen generated an average geometric mean particle size of 794 m and the 6.0-mm screen a mean particle size of 1405 m. However, hammer-mill screen size did not influence weight gain or FCR. The 6.0-mm screen size generated significantly higher starch and protein (N) digestibility coefficients in the distal jejunum ... The distance between hammer and screen should be 12 to 14 mm ( 1/2 inch) for size reduction of cereal grains. The velocity or tip speed of the hammers is critical for proper size reduction. Tip speed is the speed of the hammer at its tip or edge furthest away from the rotor, and is calculated by multiplying the rotational speed of the drive ...
