摘要： Preparation of granules by making nuclei grow, in a fluidized bed, by causing a liquid material to solidify thereon. The liquid material is sprayed in the bed upwards, with the aid of a spraying device provided with a central channel through which the liquid material is supplied, and a channel concentric therewith carrying a powerful gas stream, with the liquid material contacting the gas stream and being carried with the gas stream to a dilute zone where the growth of the nuclei takes place, which zone is created by the gas stream and is completely within the fluidized bed. The liquid material is made to come out of the central channel as a virtually closed, conical film, with a thrust exceeding the thrust of the gas stream, and this film is nebulized to very fine droplets with the aid of the gas stream.In this process a very small amount of high-energetic gas is needed, while no agglomeration occurs in the bed.

摘要： Preparation of granules by making solid nuclei grow in a fluidized bed, by causing a liquid material to solidify thereon, the liquid material being introduced into the bed from the bottom upwards with the aid of a feeding device provided with a central channel through which the liquid material is supplied and a channel concentric therewith through which a powerful gas stream is supplied, which creates a rarefied zone in the bed above the feeding device, wherein the liquid material is made to exit from the central channel into the rarefied zone as a virtually closed, conical film, nuclei from the bed are carried through the film with the aid of the powerful gas stream and next, during transport of the so moistened nuclei through the rarefied zone, the liquid material taken up by the nuclei is allowed to solidify. By this process only a small amount of high-energetic gas is required, while very little agglomeration and dust formation occurs.
