Abstract
A process for preparing low density detergent agglomerates is provided. The process involves the step of: (a) agglomerating a detergent surfactant paste or precursor thereof and dry starting detergent material having a median particle size in a range from about 5 microns to about 70 microns in a first high speed mixer to obtain detergent agglomerates having a median particle size of from about 100 microns to about 250 microns; (b) mixing the detergent agglomerates with a binder in a second high speed mixer to obtain built-up agglomerates having a median particle size in a range of from 140 microns to about 350 microns; and (c) feeding the built-up agglomerates into a fluid bed dryer in which the built-up agglomerates are agglomerated with another binder and dried to form detergent agglomerates having a median particle size in a range from about 300 microns to about 700 microns and a density in a range from about 300 g/l to about 550 g/l.
