摘要

An apparatus for granulating and/or coating particles in a spouted bed having a cylindrically shaped enclosure surrounding and extending upward from a downwardly converging frustoconical structure connected to a gas flow conduit. A downwardly inclined flange extends from the walls of the cylindrical portion to overlap the top of the frustoconical part defining an annularly extending gap therebetween for allowing finished granules to exit therethrough.
