摘要: The invention concerns a process for producing granulates by fluidised bed spray granulation and device therefor. Liquid starting substances can be converted into granulation. In order to ensure high material throughput, large number of nozzles which are also sensitive blockages encrustations must installed. makes it possible avoid the drawbacks prior art processes in that at least two partly facing (8) arranged sprayed quantities set such way their sprays meet within there is no substantial overspray on surface (4) bordering or from itself. either frontally enclose an angle less than 180°; this preferably between 150 180°. comprises flow channel (1) with lateral (8), whereby precisely staggered opposite directed bed.
