Sandvik Process Systems
� High analysis N, P and K fertilizer
� Increasing crop yields
� Lower sulphur emissions

Importance of N and S together in one fertilizer
Current crop nutrient situation
Sandvik Process Systems
� Extremely uniform (better than granules)
� No formaldehyde needed
� High product strength
� Low dust in product
� Quality significantly better than prills
� High bulk density
� Adjustable diameter: 2-4 mm

Technology features
Sandvik Process Systems
� State-of-the-art modular design
� Capacity options
� Easy maintenance
� Precise controls for dosing and mixing
Mixing unit
Sandvik Process Systems
� Perforated rotating shell
� Defined pastille size
� Excellent uniformity
High SpeedRotoform HS
Sandvik Process Systems
� Steel belt cooler with cooling water collection
� Closed hood and product piping
� Exhaust fan for transfer of emissions to the common scrubbing unit
Pastillation
Sandvik Process Systems
� Global sulphur deficiency - significant and growing
� Low sulphur levels not only limit crop yields but also decrease nitrogen efficiency
� Urea ammonium sulphate (UAS) and urea sulphur (US) are Enhanced Fertilizers
� Both can be produced efficiently by Rotoform pastillation
Conclusions
Sandvik Process Systems
UAS and US offers a win-win situation for everybody:
Win-win situation
� Higher profit margins for producers
� Higher crop yields for farmers
� Less environmental concern for all of us
