is frequently used to specify hardness. A hammer mill is typically good for grinding softer materials with Mohs hard-ness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materi-als become very abrasive; therefore, they are not suitable for high-speed hammer mills.

468 MJ/Mg for both hammer and knife mills. Hammer mill required more energy (414 MJ/Mg) than a knife mill (180 MJ/Mg) for 3.2 mm particle size. They observed that agricultural straw and corn stover required 6 to 36% of the effective specific energy required for wood. Vigneault et al. [21] observed a 13.6% saving in total specific energy

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 specific energy consumption (11.0
