130 kWh/Mg for both hammer and knife mills whereas the hammer mill required more energy (115 kWh/Mg) than a knife mill (50 kWh/Mg) to reduce the size of the hardwood chips to 3.2 mm particle size. They observed that the energy required to grind agricultural straw and corn stover was about 6–36% of the energy to grind wood.
For comminution of finer particle size ranges (20mm > P 80 > 30 μm) machines like the ball mill, vertical roller mill, hammer mill, roller press or high compression roller mill, vibration mill, jet mill and others are used. For yet finer grind sizes (sometimes referred to as "ultrafine grinding"), specialist mills .
