Compound fertilizer processing equipment according to the npk production process added nutrient composition classification: containing nitrogen, phosphorus, potassium effective components of two, known as binary compound fertilizer; Nitrogen and phosphorus, Yang three elements called ternary compound fertilizer: in addition to three nutrients, but also contains micronutrient elements called multiple compound fertilizer: in addition to nutrients, but also contains pesticides or growth hormone substances called multifunctional compound fertilizer. Using granular compound (mixed) fertilizer: Mixed compound fertilizer production line for a variety of simple fertilizer can use npk fertilizer production line, in the mixing process can be heated and added acid, ammonia containing liquid into water vapor to provide a small amount of liquid phase, in the condition of limited movement using roller granulator, disk granulator, or drum granulator, the production of compound fertilizer, the main characteristics of fertilizer, high nutrient concentration, fertilizer effect is significant.

Decompose nitrogen, phosphorus, potassium, and animal and plant residues, release nutrients, decompose insecticide and herbicide complexes, reduce fertilizer use by 30% to 50%, and increase fertilizer utilization by about 40-60%. In addition to the high bio-organic fertilizer, the use of bio-organic fertilizer will not increase the total fertilizer input, but the use of long-term bio-organic fertilizer, the total fertilizer input is likely to be less than in previous years, reducing the cost.
