We made experiments of metal pulverization using the air mills, the one formaly designed and the other of a new type, which has the characteristics : (a) the casing has a cover which can be taken off easily to inspect inside of the mill and to take out the material, (b) air is spouted out fromthe inside edge of the bearings of the propeller shafts in order to prevent the influx of lubricating oil and to protect the bearings from invasion of powder, (c) air is blown out through a hole opened on the cover to carry away the powder pulverized. By the results of the experiments we found out that the air mill can pulverize various materials and its efficiency is very high. At the same time we made clear to some extent the mechanism and the condition of pulverization by the air mill.
