Abstract
In a light powder granule treating system, a light powdery granule supplying member is connected to a light powdery granule treating member through a supply conduit, and a sensing member is arranged for detecting the light powdery granules being so stagnant within the conduit as to form a massive flow of a thickness which exceeds a predetermined value. When the sensing member detects the stagnant light powdery granules, it generates a detection signal which in turn stops the light powdery granule supplying member from operating.
