Table 1 Technical indicators of organic fertilizers
Project index
Organic matter content (on dry basis)/(%)≥30
Total nutrient (nitrogen + phosphorus pentoxide + potassium oxide) content (on dry basis)/(%)≥4.0
Moisture (free water) content /(%)≤20
Ph 5.5-8.0
Organic materials crushing (chain crusher)→composting (compost turner)→mixing compost with other ingredients (horizontal blender)→granulation(organic fertilizer granulator)→drying (rotary dryer)→ cooling (rotary cooler)→sieving (rotary screen)→ packaging (automatic fertilizer packager)
same with compound fertilizer production, organic fertilizer production process and production equipment also can be tailored just for different fertilizer plants'/factories' requirements!
