Abstract

The granulate is made by granulating a damp powdered mixture of a powdered bleach activator, a powdered granulating agent and an aqueous solution thereof and/or of another granulating agent or an aqueous solution of other active substances of washing or cleaning agents or water by means of agglomerating the damp particles in a mixing granulator and subsequently drying the damp granulate. Before the damp granulate is dried to the desired residual humidity it is taken to another unit (a rounding machine) and caused to rub against one another and on the wall and/or the bottom of the rounding machine and at the same time become compacted to the extent where the granulates, after drying, have a powder density of at least 580 g/l and especially at least 630 g/1. Besides the high powder density, the granulates exhibit an improved degree of whitening and long shelf life on mixing with bleach and alkali-containing products.
