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
