Title: (EN) Turbine agglomerated calcium hypochlorite particle
Abstract:
(EN) A feed material is obtained from mixing hypochlorous acid and a lime slurry: 2HOC1 + Ca (OH)2 ----> Ca (OC1)2.2H2O. The feed material is used to produce a hydrated calcium hypochlorite agglomerated particle that is produced in a turbine agglomerator and has a plurality of connecting links of recrystallized material bridging the small particles forming the agglomerate which has therein a plurality of pores created by the substantial evaporation of the layer of surface liquid. The surface tension and adhesion forced of the layer of surface liquid at least partially hold the agglomerated particle together prior to drying.
