Carbon Steel Rotary Drum Granulator For NPK Compound Fertilizer
Production Line
Introduction For Compound Fertilizer Production Line
Rotary drum granulator used for NPK compound fertilizer production
line is the key machine in the fertilizer producing line.Its
quality directly decides the quality and apperance of the
fertilizer.So,it’s better to choose the appropriate granulator for
you.
Raw Material For Compound Fertilizer Production Line
1. Urea,ammonium sulfate,ammonium chloride,producyion.
2. Monoammonium phosphate,diammonium phosphate,calcium
superphosphate,calcium-magnesia phosphate fertilizer
3. Potassium chloride,potassium sulphate,potassium sulphate
magnesium
