Micronized silicas are also used within the cosmetic industry. Micronized silica particles act as anti-caking and free-flowing agents which help to prevent clumping and caking during processing and storage. 5. Hydrogel Silica. Hydrogel silica is an amorphous, non-crystalline, high-quality gel that is used as a beer stabilizer.
Ball Mill (Ball Mills Explained)
If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.
