Compound fertilizer refers to the general term of fertilizer containing two or three important plant nutrient elements n, P or N, P and K. Compound fertilizer containing N, P or N, K is called binary compound fertilizer. The fertilizer containing N, P and K is called ternary compound fertilizer. In addition to the main elements of N, P and K, some compound fertilizers also contain a variety of trace elements. This compound fertilizer containing a variety of trace elements is called multi-element compound fertilizer.

The appearance of compound fertilizer is generally granular, and the color is different due to different production processes. Its main raw materials are ammonium sulfate, ammonium nitrate, ammonium carbonate, ammonium chloride, urea, potassium sulfate, potassium chloride, ammonium phosphate and so on.

Compound fertilizer has good physical properties and good dispersion when applied mechanically. The nutrient proportion of compound fertilizer varies, depending on the production method, initial composition and the requirements of fertilized plants. The compound may be organic or inorganic. Organic compounds may include fertilizers, fish and bone meal, and compost. Inorganic fertilizers combine various chemicals in the manufacturing process. Produce combinations for different crops and growth conditions.

Many production methods are being used to manufacture fertilizers.

*Mixed granulation technology. Select several kinds of fertilizer raw materials powder measured according to the need, then mix and granulate in pelleting/granulating machine.

*No-drying extrusion granulating technology. The raw materials are put into mixing machine in strict accordance with the technical requirements. Then granulate into fertilizer pellets by extrusion granulating machine.

*Bulk blending fertilizer mixing technology. The batched materials go into the feeding part of mixing system to adjust them at the best mixing state. Then enter into the unique designed mixing parts to mix the BB fertilizer raw materials fully.
