Compaction – Granulation
In this process under-sized materials convert into a continuous strip by two counter rotating rollers and then, final granules with required size are produced via a granulator. Today, this technology is used as an economical solution to produce a variety of chemical fertilizers.
Among the industries in which compaction – granulation technology is used, the following can be mentioned:
✓ Chemicals (sodium carbonate, sodium chloride, sodium sulphate, ammonium chloride, iron sulphate, …)
✓ Fertilizers (NPK, potassium chloride, potassium sulphate, potassium nitrate, micronutrients, …)
✓ Antioxidants
✓ Coal for production of activated carbon
✓ Oxides (iron oxide, zinc oxide, chromium oxide, …)
