The caking of a powder can very weak, the powder being broken down in the subsequent process stages, which is not too problematic, or can be much ...
A FEECO Coating Drum equipped with ball and tube knockers for reducing buildup. Oils, specialty chemicals, polymers, and more, are all materials frequently used as coatings in an effort to prevent caking. Coatings can also be formulated to serve other benefits as well, such as dust suppression or added nutritional value...ball mill I was given spherical porcelain grinding media, as well as cylindrical, with the instruction that the balls were for wet grinding and the cylinders were for dry grinding. My experience has been that, indeed, the porcelain cylinder- shaped media helps prevent caking of material when dry grinding. David Hendley [email protected]
