feed processors decide which mill (roller or hammer) is best suited for their grinding needs. This bulletin also contains information pertaining to the general design and operating parameters of roller mills and hammermills, and an explanation of how these mills reduce ingredient particle size. Size Reduction
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. In a typical jet mill, grinding
DEVELOPMENT AND TESTING OF A HAMMER MILL
The machine is of hammer mill type. In this case, there is hammer-like projection mounted on a shaft. The hammer revolves at high speed and grinds the materials fed into pieces by beating. Moreover, the machine can mill only the dry materials. The machine is incorporated with a detachable sieving mechanism to ensure fineness of cereal stone ground.

design and operate the opposed-jet mill’s conveying system. Note that to minimize the negative effect of the fluctuating feedrate, it’s best to control the material feedrate and airflow into the mill to maintain a solids-to-air mass-flow ratio in the mill of typically no more than 1:2. (This rule also applies to the air-assisted hammermill.)
