A fluid-bed granulator system may include a fluid-bed granulator, a scrubber unit, and a connection-duct between an air vent opening of the fluid-bed granulator and the scrubber unit. An inner surface of the connection-duct may be at least partially coated with an anti-adhesion layer. The system may further include a granulator space inside the fluid-bed granulator, a perforated plate disposed inside the granulator space, spray nozzles disposed at the perforated plate, a fluidization air inlet, supply lines for atomization air connected to the spray nozzles, supply lines for a liquid melt connected to the spray nozzles, a granulation seeds inlet, a granulator outlet opening, and an air vent opening. A disclosed urea granulation plant may utilize the fluid-bed granulator system.
