PROBLEM TO BE SOLVED: To provide a method for crushing powder-lump coagulated due to static-electricity, moisture, deaeration or the like, so as to supply a stable volume to a specific unit. SOLUTION: The method of the invention is to first carry out an aeration on coagulated powder within a hopper (36) using a fine-porous barrier membrane (60) so as to fluidize the same, followed by introducing the fluidized powder into a jet flow (84) of a pressurized gas, thereby crushing the same by virtue of the jet gas. The cracked powder thus obtained is sucked up by an ejector (18), and then pressure-supplied to a unit (16) through an air-transporting pipeline (78). COPYRIGHT: (C)2005,JPO&NCIPI
