Zusammenfassung:	Disclosed is a process for preparing crystalline sodium disilicate having a layered structure, in particular a process for preparing layered sodium disilicate by adding a small amount of water directly to cullet powder, in which the molecular weight ratio of Na2O to SiO2 is 1.80 to 2.20, as starting material to synthesize granules and introducing the granules into a rotary calcination kiln to calcine.
