Abstract:
The present invention aims to provide a method for producing granules for ceramic production, the method having high productivity and making it possible to obtain a ceramic which, when produced by press molding the granules and firing the resulting press molded product, has physical properties kept from lowering. The present invention is characterized by including: a slurry preparation step of preparing a slurry including a mixture containing a powder of an inorganic compound, a binder, and a solvent; a granulation step of introducing the slurry into a spray drying device to form a granulated substance containing the inorganic compound; an exhaust step of exhausting an atmospheric gas within the spray drying device via a cyclone having a surface made of ceramic; and a step of mixing a fine powder, which has been recovered by the cyclone during the exhaust step, with the granulated substance obtained in the granulation step.
