Double Stage Grinding And Hammer Mill
Back to Basics Hammer Milling and Jet Milling Fundamentals
A hammer mill is typically good for grinding softer materials with Mohs hardness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materials become very abrasive; therefore, they are not suitable for highspeed hammer mills. In a typical jet mill, grinding
