evaluation of a wet disc-mill system for production of fine-ground mica

A prototype wet attrition disc mil 1 was designed and operated in closed circuit at the MRL to grind mica. The mi ll utilized the principle of control- led "hydroplani ng " between two flat discs acting upon an injected mica slurry. Low bulk density of the resulting mica product indicated that this technique showed superiority over.
