摘要：Fluid-assisted granulating and coating apparatus having a circular planarmaterial circulation plate assembly rotatably mounted coaxilly within a cylindrical workarea of an upright vessel, the plate assembly including a plurality of concentric circularslots opening radially outwardly into the work area for directing a suspension fluidradially outwardly thereinto for enhanced material circulation in a circularly spiralingfashion without undesirable concentration or stagnation of charge material within thework area and without undesirable material loss through or clogging of the fluid flowslots. This remarkable effectiveness of the apparatus enables its operation under eitherfluidized or non-fluidized conditions to provide significant flexibility in controlling thecharacteristics of granules produced. Inclined radial deflection plates may be affixed tothe plate assembly for enhanced axial movement of charge material and upwardlyangled rotating impulse blades may be used with the plate assembly for opposed radialcirculation of charge material within the upper region of the work area, for enhancedmaterial circulation and increased material capacity of the apparatus.
