Abstract
A non-tower process for continuously preparing granular detergent composition having a density of at least about 600 g/l is provided. The process comprises the steps of (a) dispersing a surfactant and coating the surfactant with fine powder having a diameter from 0.1 to 500 microns in a mixer fitted with choppers, and (b) granulating the agglomerates in one or more fluidizing apparatus, wherein finely atomized liquid is sprayed onto the first agglomerates in a mixer between step (a) and (b).
