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 () is provided for rapidly and reliably removing wet powders adhering to the particle-regulating disc. The cleaning device () is provided with a cover () covered on a part of the outer circumference of a rotating particle-regulating disc. The cover () is formed with a nozzle (). The nozzle () injects a fluid to a cleaning target surface covered with the cover (). The fluid in a space formed between the cover () and the cleaning target surface is suctioned and discharged from a vacuum connection port () to the outside.
