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.

"Corundum nanoparticles, produced by the method proposed by us, are about 13 nanometers in size and are characterized by considerable porosity: one gram has a surface area of about 140 m 2.

Corundum is a crystalline form of aluminium oxide (Al 2 O 3) typically containing traces of iron, titanium, vanadium and chromium. It is a rock-forming mineral.It is a naturally transparent material, but can have different colors depending on the presence of transition metal impurities in its crystalline structure. Corundum has two primary gem varieties: ruby and sapphire.
