FORMULATION OF FERTILIZERS FOR NPK 27 – 6 – 6
The formulation of fertilizers follows controlled calculation and blending steps to achieve the target nutrient ratio.
NUTRIENT CALCULATION
Accurate calculations are essential in the formulation of fertilizers. Nutrient contents of raw materials are calculated to meet the 27 – 6 – 6 ratio in the final product.
RAW MATERIAL PREPARATION
Raw materials are weighed and prepared according to formulation calculations. Solid materials may be crushed or conditioned to improve mixing efficiency.
MIXING AND BLENDING
Uniform blending is a critical method in the formulation of fertilizers. Thorough mixing ensures that every granule of npk 27 – 6 – 6 complex fertilizers contains the same nutrient composition.
METHODS USED IN FORMULATION OF FERTILIZERS
Different methods may be applied in producing npk 27 – 6 – 6 complex fertilizers depending on manufacturing technology.
CHEMICAL GRANULATION METHOD
In this method, chemical reactions such as ammoniation are used to bind nutrients and form granules. This method ensures strong granules and uniform nutrient distribution.
PHYSICAL GRANULATION METHOD
Physical granulation involves mechanically binding raw materials into granules. This method is suitable when chemical reaction is not required.
DRYING AND COOLING
After granulation, fertilizers are dried to reduce moisture and cooled to stabilize granule structure. This step improves storage stability and product durability.
SCREENING AND RECYCLE
Granules are screened to obtain uniform size. Oversized and undersized particles are recycled back into the formulation of fertilizers process.
QUALITY CONTROL
Quality control is an essential part of the formulation of fertilizers for npk 27 – 6 – 6 complex fertilizers and includes:
-
Verification of nutrient ratios
