• In planning a feeder of fine powder it is necessary to study the characteristics of the powder to supply in order to ensure stable feeding. Especially it is the case with sticky or agglomerative powder which will often bring up feeding problems, and of which feeding in minute portions with high degree of accuracy is extremely difficult. This prototype apparatus has been developed with a view to coping with the fact that neither the conventional method of stabilizing bulk density, method of packing the powder relying on gravity into feeder mechanism, is adequate by itself for processing the supply of powder in minute portions. By mean of this prototype apparatus the powder is compressed into the groove on the roller by the rotating blade then it is scrapped off by means of a scraper. This mechanism is employed to reduce or eliminate a large fluctuation of bulk density by packing the powder with constant rate of force. As a result a very fine feeding rate as low as from one tenth gram to hundreds of grams per minute with accuracy of 1-3% has been obtained. Much finer and more accurate feeding rate will be achieved with further improvement of mechanism.
