Abstract (en)
[origin: WO9619421A1] In a chemicals crystallisation process, chemicals are at first molten then introduced into a container where they crystallise by heat extraction, are conveyed through the container and collected as a product. The process is characterised in that small, in particular monodisperse and at least partially solid particles are uniformly distributed in the container. The molten mass crystallises around said particles while they are conveyed through the container. The invention is useful for producing tablets of fertiliser.
