摘要:
A pulverization/classification apparatus includes a plurality of air nozzles, a milling chamber as a space for pulverizing particles by compressed air jetted by the air nozzles, and a rotor installed at an upper part of the milling chamber that classifies powder materials flowing into the rotor from the milling chamber with centrifuging into fine particles and coarse particles. The rotor includes plural blade members, and a width of the blade members within the rotor are set to be 1/50- 2/25 of the rotor's diameter.
