Abstract
In a spheronizer for transforming columnar granulated product, which is fed in a wet condition, into spherical shapes, irregularities on a top surface of a particle-regulating disc are easily clogged, in particular, in an outer circumference. In view of this, a cleaning device (32) is provided for rapidly and reliably removing wet powders adhering to the particle-regulating disc. The cleaning device (32) is provided with a cover (33) covered on a part of the outer circumference of a rotating particle-regulating disc. The cover (33) is formed with a nozzle (39). The nozzle (39) injects a fluid to a cleaning target surface covered with the cover (33). The fluid in a space formed between the cover (33) and the cleaning target surface is suctioned and discharged from a vacuum connection port (36) to the outside.
