ABSTRACT:
A mixture of non-agglomerated particles of condensed phosphate salt, detergent builder salt and solid chlorine-releasing agent are agglomerated (i.e. formed into composite, enlarged particles) on an inclined, generally planar sliding bed. The residence time in the agglomerator can be reduced below 2 minutes and even below one minute with no adverse effect upon chlorine stability or anti-caking properties, if at least about two moles of water (e.g. more than about 8 or 9 wt. % water) are added to each mole of condensed phosphate used in the composition prior to the time the condensed phosphate contacts the sliding bed. The resulting agglomerated particles which emerge from the agglomerator generally contain less than 25 wt. % moisture and are relatively free-flowing. They are conveyed to a drying zone and raised to a temperature of at least about 33.degree. C. in order to substantially eliminate unbound moisture and to decompose any thermally unstable hydrates (e.g. higher hydrates of sodium carbonate) which have been formed during the agglomeration step.
