  • Comminution Processes Basics And Application To

    What is the efficiency of a milling process Different possibilities to define energy efficiency 1. Specific energy of mill compared to new created surface energy not meaningful efficiency much smaller that 1 2. Specific energy of mill compared to minimum specific energy requirement in so-called element tests. However here at least two

  • 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
