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

Cadoche and López [20] tested knife and hammer mills on hardwood chips, agricultural straw and corn stover. Effective specific energy demand to reduce hardwood chips to a particle size of 1.6 mm was 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.
