Raw materials required to produce NPK are rock phosphate, potash, urea and coating agent. Phosphates, potash and urea are fed to mixer in measured quantities. Mixed material is then fed to granulator, where coating agents are added.
The granulator discharge is then dried in the dryer. The dryer discharge is then fed to cooler. Dried and cooled NPK is then fed to storage hopper. Finally, packing is done using automated machines.
