Hammer Milling and Jet Milling Fundamentals | AIChE
The Mohs scale of mineral hardness is frequently used to specify hardness. A hammer mill is typically good for grinding softer materials with Mohs hardness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materials become very abrasive; therefore, they are not suitable for high-speed ...

Effects of corn kernel hardness and grain drying temperature …
In addition, grinding the average hardness corn dried at 80 °C by roller mill at 0−0 roller-gap yielded a greater d gw than similar corn dried at 35 °C, but a different response was observed for the harder kernel corn. For hard kernel corn ground by the 30−30 roller-gap, drying at 35 °C produced larger particles than drying at 80 °C.
