PRODUCT GRANULATION UNIT Russian patent published in 2024 - IPC B01J2/14 B01J2/18 

FIELD: chemical production.

SUBSTANCE: used for product granulation. The product granulation unit includes at least one hopper for the initial product, a mill for grinding the initial product, a pneumatic classifier for classifying the ground initial product, a container for preparing a granulation solution, a disc granulator into which classified raw materials are fed from the pneumatic classifier, a fluidized bed dryer into which wet granules are fed from the disc granulator, the first classifier for the classification of dried granules, connected by product with a fluidized bed dryer, a hopper for the recycled fraction connected to the first classifier, a crusher, a second classifier for classifying the crushed product, connected by product to a crusher, a disk oiler made with the possibility of receiving the commodity fraction from the first classifier and processing the commodity fraction with a conditioning additive.

EFFECT: ensuring the stability of the formation of granulometric composition, improving the mechanical properties of the resulting granulate, and increasing the yield of the final commercial product.
