    • 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.
    • 一种造粒方法和装置,其中颗粒饲料被装入其轴线水平设置的旋转圆柱形容器(12)中,并且每个端部处的保留原料的各自的盖板(16,18)以及处理气体和 在其中旋转期间将处理液体进入容器。 气体从其来源通过供应管道(34)供应,并且通过至少一个排放导管的端口装置(44,48)在容器(12)的进料材料(38)的床内排出 与所述供应管道34连通的管道42在所述容器(12)内纵向延伸并且被固定成与所述容器(12)不旋转; 并且选自要造粒的固体的溶液,悬浮液和熔体中的处理液体从在容器(12)中纵向间隔开的喷雾(59)分布在进料床床的表面上,以实现进料材料 ,处理气体和固体和原料的形成颗粒的液体。
