Grinding energy and physical properties of chopped and,
conducted in two stages: (1) a chopper without a screen, and (2) a hammer mill using three screen sizes (19.05, 25.4, and 31.75 mm). The lowest grinding energy (1.96 and 2.91 kWh t 1) was recorded for canola straw using a chopper and hammer mill with 19.05-mm screen size, whereas the highest (3.15 and 8.05 kWh t 1) was recorded for barley and oat straws.Optimizing hammer mill performance through screen,,Hammer mills are recognized as technology capable of finely grinding the greatest variety of materials Bitra VSP, Womac AR, Chevanan N et al.

Why process at all? Of course, the answer is ultimately feed efficiency, producing the most milk, eggs, meat or fiber at the lowest possible cost.
