Abstract: A method for processing of granules, by forming at least one injection zone in a fluidized bed where a feed stream of seed particles is contacted or coated by a liquid product by simultaneous injection of the feed stream of the seed particles and a feed stream of the liquid product, forming at least one granulation zone in the fluidized bed where the contacted or coated seed particles may be at least one of dried, shaped, and cooled to form granules, extracting the granules from the at least one granulation zone and sorting the extracted granules into undersize granules, on-size granules, and oversize granules, passing the on-size granules to post-processing treatment, removing the oversize granules, and passing the undersize granules back into the feed stream of the seed particles, wherein the extracted granules are made to pass through at least one classifier located in the at least one granulation zone.

Abstract: This invention relates to a method and device for processing of granules of solidified salts, by forming at least one injection zone in a fluidised bed where a feed stream of seed particles is contacted/coated by the liquid product by simultaneous injection of a feed stream of the seed particles and a feed stream of the liquid product to be sprayed, forming at least one granulation zone in the fluidised bed where contacted/coated seed particles may be dried and/or shaped and/or cooled to form granules, extracting granules from the at least one granulation zone(s) and sorting the extracted granules into three fractions; undersize granules with too small diameters compared to the desired size range, on-size granules with diameters within the desired size range, and oversize granules with too large diameters compared to the desired size range, passing the fraction of on-size granules to post-processing treatment for forming the product granules, removing the oversize, typically by reducing the size of at least a fraction of the oversize granules and admixing them with the fraction of undersize granules, and passing the fraction of undersize granules into the feed stream of seed particles, wherein the granules are made to pass through at least one classifier placed in the at least one granulation zone(s) of the fluidised bed, which segregates the granules according to their size and which passes at least a part of the segregated undersize granules back into the injection zone(s) for further enlargement. The invention also relates to a granulator for performing the inventive method.
