ABSTRACT:
A process and apparatus are described for the continuous granulation of high-density detergent granules of a predetermined size from a detergent powder, with the granulation apparatus comprising a granulation chamber, a feeding port located at the top of the granulation chamber, a first discharging port located at the bottom of the granulation chamber including valve means for opening and closing the port, a second discharging port located at the side wall of the granulation chamber, one or more horizontally rotating stirring blades attached to a rotational shaft positioned at the bottom of the granulation chamber which stir and mix the detergent powder, and one or more vertically rotating grinding blades located above the one or more stirring blades and attached to a rotational shaft positioned at the side wall of the granulation chamber which grind and classify coarse detergent particles; and the process comprising the steps of continuously feeding a detergent powder into the granulation chamber, granulating the detergent powder by stirring and mixing the powder with the one or more horizontally rotating stirring blades, and continuously discharging the high-density detergent granules thus formed through the second discharging port.
