Abstract:
(EN) The invention relates to a method for producing prills (1), in particular fertilizer prills, which are coated with at least one biodegradable polymer layer (1.3, 1.5), in particular a PLA layer. The at least one biodegradable polymer layer is applied onto a carrier material (1.1) of each prill, and the prill (1) is first coated with at least one first biodegradable layer (1.3) on the carrier material (1.1) in a drum-coating coating step, in particular in a drum coater (13) at a relative negative pressure, and then with at least one second biodegradable layer (1.5) over the first layer in a whirl-coating coating step, in particular in a whirl-coating coater (15) at a relative positive pressure. The invention additionally relates to an assembly for producing coated prills and to prills which are obtained using said assembly.
(FR) L’invention concerne un procédé de production de granulés (1), en particulier de granulés fertilisants, revêtus d’au moins une couche polymère dégradable (1.3, 1.5) biologiquement, en particulier d’une couche PLA, la ou les couches polymères dégradables étant appliquées sur un matériau de support (1.1) du granulé concerné, les granulés (1) étant tout d’abord revêtus d’une première couche dégradable (1.3) sur le matériau de support (1.1) dans une étape de revêtement en tambour, en particulier dans un tambour de revêtement (13) sous vide relatif, puis revêtus d’une seconde couche dégradable (1.5) par-dessus la première couche dans une étape de revêtement en lit fluidisé, en particulier dans un lit fluidisé de revêtement (15) sous vide relatif. L’invention concerne par ailleurs un système de production de granulés revêtus et les granulés ainsi obtenus.
(DE) Die Erfindung betrifft ein Verfahren zum Herstellen von mit wenigstens einer biologisch abbaubaren Polymer-Schicht (1.3, 1.5), insbesondere PLA-Schicht beschichteten Prills (1), insbesondere Düngemittel-Prills, wobei die wenigstens eine abbaubare Polymer-Schicht auf ein Trägermaterial (1.1) des jeweiligen Prills aufgebracht wird, wobei die Prills (1) zunächst in einem Trommelcoating-Beschichtungsschritt mit wenigstens einer ersten abbaubaren Schicht (1.3) auf das Trägermaterial (1.1) beschichtet werden, insbesondere in einem Trommelcoater (13) bei relativem Unterdruck, und daraufhin in einem Wirbelcoating-Beschichtungsschritt mit wenigstens einer zweiten abbaubaren Schicht (1.5) über die erste Schicht beschichtet werden, insbesondere in einem Wirbelschichtcoater (15) bei relativem Überdruck. Ferner betrifft die Erfindung eine Anordnung zum Herstellen von beschichteten Prills sowie damit erhaltene Prills.
