Mill scale - Wikipedia

Mill scale, often shortened to just scale, is the flaky surface of hot rolled steel, consisting of the mixed iron oxides iron oxide, iron oxide, and iron oxide. Mill scale is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling red hot iron or steel billets in rolling mills. Mill scale is bluish-black in color. It is usually less than 0.1 mm thick, and initially adheres to the steel

Back to Basics Hammer Milling and Jet Milling Fundamentals

The Mohs scale of mineral hardness is frequently used to specify hardness. 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 action ...
