A New Method (Ball Milling and Sodium Sulfide) for Mechanochemical ...
The ball mill treatment reduced chromite grains greater than 15.77 µm down to sizes less than 11.15 µm in diameter, and thus released chromite-bound Cr(VI) for sulfide reduction. Magnesioferrite encapsulated Cr(VI) was released and reduced similarly with grain size change from 15.77 to 37.5 µm to below 15.77 µm. Besides, the improved 10% of ...

Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion, the particles in between the media and chamber walls are reduced in size by ...
