Thus, it was confirmed that one of the advantages of jet mill is the reduced damaged starch promoted in comparison to other milling processes. Hossen et al. reported that jet milled white rice flour with d50 45 μm had less starch damage than rice flour processed by a hammer mill, with d50 53 μm, in spite of similar mean size.

Media Milling, Dry and Wet. Ball milling, or media milling, uses collision and shear forces to grind down material, whether wet or dry. A ball mill can operate at either high or lowenergy outputs, and material characteristics can span a wide range. Adjustable variables include ball types and sizes, speeds, material mass in slurry, and more.
