Manufacturing Process -
How we make Crystalline Ammonium Sulphate (NH4)2 SO4

Crystalline ammonium sulphate is manufactured in a neutralizer-crystallizer unit. This process involves the neutralization of sulphuric acid with ammonia. The resultant slurry is evaporated to a crystal formation. Crystal size is controlled by flow rate and pH of the slurry. Crystals are separated from the slurry by centrifuges and dried to 0.2% water in rotary driers. Dry crystals are screened into the grades designed to meet customers' needs for direct application or blending.

Benefits

  • sulphate is immediately available to the crop
  • high analysis reduces handling requirements
  • application flexibility; broadcast, band or seed place
  • consistent quality and relatively dust free
