Popis:	In the exhauster that feeds the boiler furnace with fuel in the mill, the blades of the exhauster wear out violently due to the pulverized coal-air mixture treated in it. As a countermeasure against this wear phenomenon, it is more effective to adopt lacerated blades instead of common straight blades than to change the material of blades. This report aims to provide a basis of wear-proof measure by grasping the motion of the pulverized-coal in the exhauster. As the result of the experiment, the following conclusions were drawn : (1) In case of the straight blades, most of the powder flows along the blade surface. (2) In case of the lacerated blades, the powder flows from the tips of lacerated teeth drawing a parabolic line, but hardly touching the blade surface.
