Back to Basics Hammer Milling and Jet Milling Fundamentals. 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.

08-12-2016The goal is to keep the part (1) in contact with the regulating wheel and (2) rotating at a slower speed, while the faster, larger abrasive grinding wheel applies the force that creates the precise roundness of the part. Using the correct wheel angles helps to ensure that the entire surface of the grinding wheel is in use.

Abstract. There are many types of grinding: "precision" and "rough," internal, external, surface, centerless; using wheels or belts; and conventional or "super" abrasives. I believe they all act the same. When a moving abrasive surface contacts a workpiece, if the force is high enough, material will be removed from the part and the
