The NPK fertilizer production line using extrusion granulation with a roller press granulator is a common process for manufacturing nitrogen-phosphorus-potassium compound fertilizers. Process Flow of NPK Fertilizer Production Line by Extrusion Granulation with Roller Press Granulator.The process mainly relies on mechanical pressure to granulate materials, without the need for high-temperature melting or excessive moisture addition.
