Fertilizer Production Process and Flow – What is the Moisture Content of Compound Fertilizer Granulation Feed?
What is the Moisture Content of Compound Fertilizer Granulation Feed? The moisture content of compound fertilizer granulation feed is not a fixed value, but depends on the granulation process used. For extrusion granulation (dry granulation), it is recommended to control the feed moisture content between 2% and 4%, which is the optimal range to ensure granule quality and stable equipment operation. For wet granulation processes such as disc granulation and drum granulation, the feed moisture content typically needs to be controlled between 8% and 28%. Therefore, the "2%–4%" range mainly applies to extrusion granulation scenarios.
