<p>An apparatus for finely milling powder is provided to reduce the whole volume of the apparatus and simplify structure of the apparatus by forming a milling chamber within a compressed air room in which compressed air is filled. An apparatus for finely milling powder comprises a milling chamber(20) into which powder material is injected to be milled, and which is formed within a compressed air room filled with high pressure air, and a partition(21) which divides the compressed air room and milling chamber, and in which fine spray holes(21a) are formed to spray compressed air into the milling chamber. The milling chamber has a hole formed in ceiling and bottom central parts thereof respectively, a discharge pipe(80) for discharging milled powder is connected to the hole in the ceiling of the milling chamber, and a pitch(30) passing through the milling chamber to open or close the discharge pipe is screwed to the hole of the bottom of the milling chamber.</p> |
