METHOD FOR CLASSIFYING POWDER

摘要

A method for classifying powder using a fluid classifier includes: a mixing step of mixing a powder with an auxiliary agent made of an alcohol (step S10); a feeding step of feeding the powder mixed at the mixing step into the fluid classifier (step S22); a heating step of heating a gas (step S14); a supplying step of supplying the gas heated at the heating step to the fluid classifier (step S16); and a classifying step of classifying the powder in the fluid classifier based on a particle diameter (step S24).
