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. In a typical jet mill, grinding

tends to be inflated before grinding due to a large quantity of air trapped in among the light charcoal particles. As milling progresses, this air is forced out and the material volume decreases. To account for this fact, a higher material charge is necessary when milling mixtures containing charcoal and other compounds that seem overly fluffy.
