  • Response to Comment on “High-surface-area

    When micrometer-sized preformed corundum is milled, it is also severely contaminated with milling media and jar material. Our approach reported in ( 1 ) presents a simple procedure, enabling easy access to high-surface-area α-Al 2 O 3 , from which impurities, if any, can easily be removed, or can be avoided altogether, if milling proceeds in ...

  • The History and Importance of Stone Milling Royal

    The roller milling, or “high grinding” method slowly replaced most existing traditional stone mills. With roller milling, steel rollers quickly explode the grain over a series of passes through the mill. The reground flour is thoroughly sifted to remove the bran and germ, thereby also removing some of the nutrients.
