How to Make Commercial Organic Fertilizer?

Raw materials pre-crushing (high moisture fertilizer crusher) → Organic materials fermentation (groove type compost turner) → Fermented materials crushing (high moisture fertilizer crusher)→ Granulating (rotary drum granulator) → Drying (rotary drum dryer) → Cooling (rotary drum cooler) → Finished products screening (rotary drum sifting machine) → Sub-standard granules crushing (vertical fertilizer chain crusher) → Coating (rotary drum coating machine) → Finished products packing (automatic quantitative packager) → Storage (storing in a cool dryplace, tightly closed)
