摘要： A centrifugally rolling granulating and coating device (1), comprising a fixed wall (7) of which horizontal section part (7a) in contact with powder and granular material (2) is formed in circular shape and a rotating disk (5) which is installed inside the fixed wall (7) at a distance (12) and rotated horizontally by a motor (13), wherein an air feeding device (21) to feed dry air (22) to the upper surface of the rotating disk (5) is installed on the rotating disk (5), the air feeding device (21) comprises a cylindrical straight pipe part (25) and a conical air inlet port (23) and installed movably vertically in a centrifugal flow chamber (6) and, during a granulating process, the air feeding device (21) stops feeding the dry air (23), waits at an upper position (H), lowers to a lower position (L) after the granulating treating has been completed, and feeds the dry air (22) onto the rotating disk (5) to dry the granule, whereby spherical particles small in grain size, small in grain size distribution width, and high in sphericity can be produced efficiently in a single device.
