Fertiliser production combines pneumatic conveying, granulation, drying and bagging, all in an atmosphere that is both dusty and chemically aggressive. The compressed air system must be robust, corrosion-resistant and reliable enough for continuous operation.
Key applications
- Pneumatic conveying of raw materials and product
- Granulation and prilling process air
- Bag filling, sealing and palletising
- Control and valve actuation
Air quality
Instrument air must be dry and oil-free at low dew point for reliable control. Process and conveying air need drying and filtration, with particular attention to preventing moisture from caking hygroscopic fertiliser.
Specification notes
Choose corrosion-resistant coolers and coatings for the chemical atmosphere, and heavy-duty intake filtration for dust. Redundancy and continuous monitoring keep production running, because fertiliser plants are hard to stop and restart cleanly.
