Green Granulation is a world leading provider of fertilizer related process technologies, offering urea granulation and other fertilizer-related technologies. It is also the owner and developer of the state-of-the-art Cold Recycle Fluid-Bed Urea Granulation Technology (CRG) process. The patented CRG process was first successfully applied in a plant in China in 2013.
The Cold Recycle Granulation process is modernizing the Urea Granulation world; offering energy saving, low investment costs and high product quality by using a ground shaking new layout and revolutionary production process.  
 
 
Characteristics and advantages of the Cold Recycle Granulation process
 
Low energy consumption thanks to:
* reduced product layer thickness resulting in less heating of the fluidization air fan and consequently reduced amount of needed air
* hydraulic urea sprayers use reduced amount of atomization air at reduced pressure
* low pressure drop scrubbers reduce the power consumption of the exhaust air fan(s)
* reduced amount of recovered urea dust combined with lower water content of the urea solution, typically 55% due to low atomization air and higher granulator scrubber temperature
 
Low investment thanks to:
* low building height, typically 27m total height
* low requested building strength, highest load bearing floor is at the granulator bottom at 17m, vibrating screens are located below the granulator
* reduced granulator and cooler strength because of low fluidization air fan pressure and low scrubber exhaust fan suction pressure
* bucket elevator capacity is only 30% of standard, lifts only fines and crushed product
* reduced air ducting, air enters the scrubbers from the top and leaves the scrubbers from the side
 
Improved product quality thanks to:
* low product moisture due to the combination of the Green Granulation hydraulic sprayers / sprayer layout
* low end product dustiness due to slow cooling and highly improved product polishing in the cooler
