2013-11-1 · A Micron-Master Jet Pulverizer jet mill (0.61 m in diameter)was used in this study to grind the materials as shown in Fig. 1a and b. The materials to be ground were blended for 60 min in a 0.19 m 2 V-blender (this step is only conducted for blends). After blending, approximately 45 kg of the pre-blended material was transferred into the hopper for jet mill grinding.

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
