<p>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, while wetting the surfactant coated with the fine powder with finely atomized liquid, in a mixer, and (b) thoroughly mixing the agglomerates in a mixer. Step (b) can also be followed by further step (c), i.e., granulating the agglomerates from step (b) in one or more fluidizing apparatus.</p> |
