ABSTRACT:
A process for preparing high density detergent agglomerates having a density of at least 650 g/l is provided. The process comprises the step of continuously mixing detergent granules having a density of less than about 450 g/l in a moderate speed mixer/densifier wherein the granules are pulverized and densified to produce agglomerates having a density of at least 650 g/l . The mean residence time of the granules in the moderate speed mixer/densifier is at least about 12 minutes, and preferably from 12 to 15 minutes. The process further includes the step of either spraying a binder or adding a coating agent in the mixer/densifier to facilitate agglomeration of the granules. Thereafter, the agglomerates are dried to obtain the high density granular detergent agglomerates which are ready for packaging as a low dosage detergent.
