Abstract: The invention relates to a process for preparing spherical granules from pulverulent solids and the granules prepared by the process. The process is characterised, inter alia, in that the pulverulent solids, if required together with the binders, lubricants and plasticisers conventional for pressing solids are uniformly moistened by addition of an appropriate amount of liquid and mixing in a mixer, pressed in a ring matrix press to give cylindrical agglomerate rods and then rounded in a rounding unit having a fluted disc. The solids granulated by this process exhibit a very narrow grain size spectrum and are distinguished, depending on process conditions, by good flowability and good dispersibility.

Abstract: Preparation of a fermented sludge for use as an animal feed additive which contains a fermentation product, comprises granulation, compaction and drying of the sludge in a fluidised bed, at the same time as introducing extra mechanical energy above that needed to fluidise the bed particles, in order to achieve the desired additive particle size and bulk weight.
