Abstract

A fluid-bed granulator system for producing fertilizer granules with a defined size including a fluid-bed granulator, a first cooler externally connected with the fluid-bed granulator or forming an internal part of the fluid-bed granulator, and a product screen connected with the first cooler. The product screen includes an exit for on-size particles; an exit for oversized particles and an exit for undersized particles. The exit for undersized particles is connected to the fluid-bed granulator and the exit for oversized particles is connected to the fluid-bed granulator via one or more crushers. The exit for on-size particles is connected to a first splitter. The first splitter is connected to the fluid-bed granulator and a post processing unit. A particle size analyzer is located between the fluid-bed granulator and the product screen.
