摘要： A method and apparatus for granulation in which particulate feed material is charged into a rotary cylindrical vessel (12) having its axis disposed horizontally, and respective cover plate (16,18) at each end for retaining the feed material, and a treatment gas and a process liquid is passed into the vessel during rotation of the latter. The gas is supplied from a source thereof, via a supply pipe (34), and discharged within a bed of the feed material (38) in the vessel (12) through port means (44,48) of at least one discharge conduit (42) which is in communication with the supply pipe (34), extends longitudinally within the vessel (12) and is fixed against rotation with the vessel (12); and the process liquid, selected from solutions, suspensions and melts of solids to be granulated, is distributed over the surface of the bed of feed material from sprays (59) spaced longitudinally in the vessel (12) to effect heat transfer between the feed material, the treatment gas and the liquid for formation granules of the solid and feed material.

摘要： A method and apparatus for processing particulate material charged into a rotary cylindrical vessel (12) having its axis inclined to the horizontal so that one end thereof is raised relative to the other end, and having a respective annular cover plate (16,18) at each end defining a central opening at its end (17,19), the material being charged through the opening (17) at the one end thereof and caused to progress along the vessel (12) and discharge therefrom through the opening (19) at the other end by rotation of the vessel (12). Gas for processing the material is passed into the vessel (12) during rotation of the latter, the gas being supplied from a source thereof, via a supply pipe (34), and discharged within the material (38) in the vessel (12) through port means (44,48) of at least one discharge conduit (42) which is in communication with the supply pipe (34), extends longitudinally within the vessel (12) and is fixed against rotation with the vessel (12); the quantity of material (38) progressing along the vessel (12) being sufficient to cover the at least one conduit (42).
