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 …Web

On average, the operation of biomass chopper required five times more energy than chopping of biomass. On the other hand, the grinding of biomass required on an average three times more energy than operation of hammer mill. Interestingly, almost the same amount of energy was required to operate the pellet mill and production of pellets.Web
