Title: POTASSIUM NITRATE CO-PRODUCTION TOWER MELT MICROPRILLED WATER-SOLUBLE FERTILIZER AND METHOD OF PREPARING SAME
Abstract:
Disclosed are a potassium nitrate co-production tower melt microprilled water-soluble fertilizer and a method of preparing same, which belong to the technical field of water-soluble fertilizer production. The potassium nitrate co-production tower melt microprilled water-soluble fertilizer is prepared from potassium nitrate concentrate, urea, industrial monoammonium phosphate, water-soluble ammonium polyphosphate, potassium sulfate, EDTA-Fe, EDTA-Zn, EDTA-Mn, boric acid and ammonium heptamolybdate. The potassium nitrate co-production tower melt microprilled water-soluble fertilizer product has balanced and stable nutrients. The product is of a microprilled shape with a smooth appearance, not prone to hardening and helpful for being absorbed and utilized by crops, and contains a full range of nutrients. In addition, the adopted automatic batching equipment production process integrates mainly batching, mixing and packaging, each of which is fully automated. The process is environmentally friendly, energy saving, and easy for production.
