mer mill operation but not for jet mills. Melting point and thermal instability. Jet mills can grind materials with low melting points effectively because these mills have intrinsic cooling due to compressed air expan-sion in the body of the mill. With the help of sweeping air, hammer mills may also be able to process materials with low

3. Hammer mills work in the principle that most materials will crush, shatter, or pulverize upon impact. 4. The Process: Material is fed into the mill grinding chamber through the feed chute, typically by gravity. It repeatedly is struck by ganged hammers which are attached to a shaft which rotates at high speed inside the mill chamber.

Cadoche and López (1989) tested knife and hammer mills on hardwood chips, agricultural straw and corn stover. Energy consumption to reduce hardwood chips to a particle size of 1.6 mm was 130 kWh/Mg for both hammer and knife mills. The hammer mill required more energy (115 kWh/Mg) than a knife mill (50 kWh/Mg) for 3.2 mm particle size.
