Agrochemicals and fertilizer

Comprehensive separation solutions

The need to serve growing global populations while meeting stringent environmental regulations is more pressing than ever before. To meet these conflicting challenges, most of the world’s leading agrochemical and fertilizer producers rely on ANDRITZ SEPARATION to ensure reliable uptime and efficiency in mechanical and thermal separation processes.

Proven reliability and expertise

Every day, ANDRITZ SEPARATION installations are ensuring the highest levels of safety and control for customers like BASF, Bayer, and Syngenta. Within agrochemicals, many already depend on the industry’s largest batch machines, developed by ANDRITZ SEPARATION to achieve the highest throughput at the lowest cost of ownership. 

For urea, potash, and ammonium sulfate, our world-scale single-line dryers help to achieve the right moisture content with the maximum possible productivity, and our screen bowl decanters, pusher centrifuges, and vacuum disc filters are key to reliable operations.

Profitable high-volume production

In the world of phosphoric acid, production volumes can be staggering. And since our tilting pan filters produce more than 80% of all phosphoric acid in the U.S., we know exactly how quickly your savings can add up. Energy efficiency is always critical, and downtime is unacceptable. 

Our tilting pan filter‘s flood-washing capabilities are designed to ensure maximum extraction of water-soluble P2O5 with the lowest possible operating costs. Even smaller plants can achieve significant efficiency gains with our horizontal belt filter. Thanks to deep process expertise gained by close collaboration with the world’s largest producers, ANDRITZ SEPARATION ensures the most profitable and sustainable separation processes.
