Comminution Properties of Biomass in Hammer Mill and its

Cadoche and López () 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.

Back to Basics Hammer Milling and Jet Milling Fundamentals

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.
