COMPARISON OF ENERGY EFFICIENCY BETWEEN A ROLLER MILL …
For roller mill grinding, roll gap was the most significant factor affecting energy requirement, followed by the roll speed differential. For hammer mill grinding, screen opening size had the most significant effect. For both mills, feed rate was not significant; and energy efficiencies were about the same.

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

Milling vs. Grinding - obsidianmfg
Milling says : Avoid interrupted cuts. An interrupted cut is one where the tool alternately enters and leaves the workpiece during the cut. Because cast iron has relatively low tensile strength, the tendency of the cutting forces it to break out the edge of the casting as the tool leaves the work.
