    摘要： A granulated fatty alcohol sulphate is characterized by a bulk density greater than 600 g/lit when no consolidation stress is imparted, it has a particle size-distribution such that at least 15% of the particles are larger than 1000 .mu.m, and less than 10% of the particles are smaller than 250 .mu.m, and has a bulk density which is dependent on the consolidation stress in the range 200 kg/cm.sup.2 to at least 750 kg/cm.sup.2.

    摘要： A process for producing a granular detergent composition containing a surface active agent, a zeolite, an alkali metal silicate, and other detergent builder is described. This granular detergent composition is produced by either (1)(a) preparing an aqueous slurry containing, as a dispersing medium, the surface active agent;(b) bubbling a gas into the aqueous slurry to form a slurry containing bubbles having an average bubble diameter of 40 through 100 microns and having a specific gravity of 0.7 through 0.9;(c) mixing the resultant aqueous slurry with the zeolite, the alkali metal silicate, and the other builders to form a detergent slurry; and(d) spray drying the detergent slurry to form the granular detergent composition or (2)(a) preparing a detergent slurry containing the surface active agent, the zeolite, the alkali metal silicate, and/or other detergent builders;(b) passing the detergent slurry through a centrifugal pump, while a gas is bubbled into the detergent slurry, whereby the detergent slurry containing bubbles having an average diameter of 40 through 100 microns and having a specific gravity of 0.7 through 0.9 is formed; and(c) spray drying the detergent slurry to form the granular detergent composition.

    摘要： A method has been found for increasing the silicate content in spray dried detergents without decreasing the spray dryer throughput. The method involves the preparation of detergent slurries with high solids content by adding alkali metal silicates to the slurries in the form of sodium-potassium double silicate glass. Thus, the amount of water that must be removed in the drying tower is reduced and/or the silicate content can be increased when compared with slurries prepared with sodium silicate solutions.

    摘要： A method is provided for spray-drying large volumes of a synthetic detergent slurry which comprises spraying the slurry into the spray-drying chamber in at least two different levels of uniformly spaced atomizing nozzles. The lowest level of nozzles is critically positioned at a point in the spray chamber below a 190* F. isotherm and above a boiling point isotherm. From 30 to 80 percent of the slurry is atomized at this lowest level. The balance of the same slurry is sprayed through the remaining levels. Apparatus is provided for practicing this process.
