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

Hammermills versus roller mills | World-grain ...

By using a roller mill, or adopting roller grinding principles as part of the feed mechanism on entry to the hammermill, the raw material is partially ground at that point, which then allows the hammers and screens in the grinding chamber of the hammermill to be fully effective, with often excellent grinding efficiency results.
