We have been involved in the fertilizer industry since the mid-1980s when urea was successfully pastillised for the first time at one of our R&D centers. In the years since, we have established ourselves as a leading provider of finishing technologies to the fertilizer market.
These systems include the Sandvik Rotoform®, a fast, efficient and clean method of converting fertilizer melts into uniform pastilles in a single step, and one that provides an ideal solution for fertilizer producers looking to de-bottleneck or revamp existing process facilities, or reduce overall emissions.
A key benefit of the Rotoform process is the ability to produce pastilles with a high crushing strength without the addition of formaldehyde. This enables the efficient and economical production of technical grade urea for applications including animal feed, pharmaceutical products and Diesel Exhaust Fluid (DEF) used in Selective Catalytic Reduction (SCR) to lower NOx concentration, commonly referred to as AdBlue.
Upstream mixing solutions
Complementing our Rotoform solidification technology, we supply a range of upstream solutions including blending and grinding units. These can be used to combine liquid and solid products into suspensions, enabling the production of speciality urea products such as:
- Urea + sulphur
- Urea ammonium sulphate (UAS)
- Urea + potassium
- Urea blended with micro-nutrients
Other special fertilizers that can be produced on these systems include ammonium nitrate and additives, and sulphur bentonite.
The wealth of experience and engineering know-how that exists across Sandvik means we can deliver complete turnkey installations including control systems, information technologies and electrical services.
This integrated design capability also covers:
- Mixing / grinding lines
- Dosing / measuring equipment
- Heated tanks and pipework
- Pumps, chillers and cooling towers
- Elevators / conveyors
- Storage silos
- Bag filling systems
We can therefore provide complete end-to-end systems for the mixing, solidification and downstream handling of a wide range of products including fertilizer urea, technical grade urea and speciality urea products such as UAS.

Flexible production of urea + sulphur fertilizers and other enhanced fertilizers
It is now accepted that multi-nutrient fertilizers have the potential to deliver a number of significant benefits, not only to farmers but also to the environment as a whole. To see why, it's important to understand the current crop nutrient situation.
