Back to Basics Hammer Milling and Jet Milling …
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
