METHOD FOR CLASSIFYING POWDER

摘要

Provided is a method for classifying a powder using a classifier, wherein the method comprise: a mixing step for mixing a powder and an auxiliary agent formed from an alcohol aqueous solution containing 10 to 50 masses of an alcohol; an introduction step for introducing the powder mixed in the mixing step to the classifier; a heating step for heating a gas; a feed step for feeding the gas heated in the heating step to the classifier; and a classifying step for classifying the powder in the classifier on the basis of grain size.
