Jun 16, 2020 Increasing hammer tip speed increased linear, P 0.001 AoR. Increasing screen hole diameter decreased linear, P 0.001 AoR. In summary, the particle size range for a specified hammermill screen size can be adjusted through manipulation of the hammer tip speed, which is made possible using motor variable frequency drives.
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 action is caused mainly by particle-particle collisions, so wear to the mills internals is less of an issue.
