Granular sodium dichloroisocyanurate is made by forming sheets of sodium dichloroisocyanurate containing from 11.0 to 14% of combined water, by feeding sodium dichloroisocyanurate powder between sets of rolls at pressures of the order of 7,500 +/- 50% pounds of force per linear inch of contact line, breaking up the sheets to produce a mixture of powder and granules, and then screening the broken-up mixture to get the desired granules. The granular material may be dried, if desired, to anhydrous granules, or used in hydrated form.
