The final phase of fertilizer production takes place at the granulation plant. In a carefully controlled environment, the phosphoric acid produced is combined with the liquid ammonia to form ammonium phosphate slurry. This slurry is then pumped into the granulator where it forms granules of fertilizer, which are then dried, screened and coated.

Stainless steel is the common name for a large group of ferrous alloys that are resistant to rust. Unlike other iron alloys, stainless steel has a stable passivation layer that protects it from air and moisture. This rust-resistance makes it a good choice for many applications, including outdoor, aqueous, food service, and high-temperature uses.

Carbon steel is often used to contain fertilizers because it is cheap, but adequate surface cleaning, preparation and coating are necessary. Type 304 Stainless Steel has shown overall benefit for liquid fertilizer service over three-year service tests. Penetration figures for tanks exposed for 2 years to commercial liquid fertilizers are
The 304 and 316 stainless steels are most commonly used in handling liquid fertilizers. The nickel content in stainless steel imparts toughness and corrosion resistance, and the chromium forms a thin oxide film, protecting the surface from corrosion attack. Although resistant to a wide range of chemicals, they are prone to stress corrosion ...
