Abstract
A powder-classification method includes a mixing step in which a powder and a liquid additive are mixed together, a drying step in which the powder mixed in the mixing step is dried, a loading step in which the powder dried in the drying step is loaded into a fluid classifier, a heating step in which a gas is heated, a supplying step in which the gas heated in the heating step is supplied to the fluid classifier, and a classifying step in which the powder is classified in the fluid classifier based on a grain size of the powder.
Claims11
A powder-classification method comprising:
- a mixing step in which a powder and a liquid additive are mixed together;
- a drying step in which the powder mixed in the mixing step is dried;
- a loading step in which the powder dried in the drying step is loaded into a fluid classifier;
- a heating step in which a gas is heated;
- a supplying step in which the gas heated in the heating step is supplied to the fluid classifier;
- and
- a classifying step in which the powder is classified in the fluid classifier based on a grain size of the powder, wherein
- a drying temperature and a period of time for drying in the drying step are each determined based on a flash point of the liquid additive.
