1286592 Wet pelletizing CABOT CORP 28 Jan 1970 [3 Feb 1969] 4026/70 Heading B5A Pellets are produced from pulverulent material, e.g. carbon black, by agitating the material and a liquid to agglomerate the pulverulent material into coherent pellets and heating the inner surfaces of the housing walls through the housing sufficiently to prevent substantial build-up of caked solid matter on the inner surfaces. The walls are preferably heated to at least 150‹ F. by hot water or steam in a jacket or serpentine of metal bonded to the exterior surface by a thermally conductive adhesive.
