Abstract

Den foreliggende oppfinnelse angår en fremgangsmåte for fremstilling av fritt-strømmende pulvere av granulære aggregater av ikke-pigmentært titandioxyd. Fremgangsmåten omfatter tilveiebringelse av tørkede forformer av flokkulert pigmentært titandioxyd og fin-. deling av disse til pulvere av granulære aggregater med øket bulktetthet og på forhånd bestemt partikkelstørrelse.The present invention relates to a process for the preparation of free-flowing powders of granular aggregates of non-pigmented titanium dioxide. The process comprises providing dried preforms of flocculated pigmented titanium dioxide and fines. division of these into powders of granular aggregates with increased bulk density and predetermined particle size.
