Bulk blending fertilizer, also known as BB fertilizer, is composed of two or more granular high concentration raw material fertilizers, which are mixed according to the user's needs in a certain proportion. This kind of fertilizer seems uneven in appearance, but its nutrient is equivalent to other compound fertilizers in effect. In the production of bulk blending fertilizer, all the raw material fertilizers must be granular, and the size of the granules is basically similar, so as to prevent the same granules from aggregating in the production, storage, transportation and use of mixed fertilizer and the single fertilizer effect.
Application of bulk blending fertilizer
bulk blending fertilizer formula can be flexibly adjusted, especially suitable for use in areas with large land area, complex soil types and diverse crop types. It has been widely used in the developed United States, accounting for about 40% of the total fertilizer consumption.
Raw material of bulk blending fertilizer
Bulk blending fertilizer, like other compound fertilizers, has three grades: high, medium and low. The raw materials used are urea, ammonium nitrate, ammonium chloride, ammonium bicarbonate, calcium superphosphate, monoammonium phosphate, diammonium phosphate, phosphate nitrate, potassium chloride and potassium sulfate.
Fertilizer granulating production line processes different types of fertilizer particles. Various granular products made by the fertilizer granulating production line process, which are mixed into different types of special blended fertilizers through the bulk blending fertilizer machine. Bulk blending fertilizer machine includes multiple silos batching system, bulk blending fertilizer mixer, packaging machine. The BB fertilizer mixer is the main equipment for producing this kind of fertilizer. It mixes the different granular fertilizers evenly and ensures the fertilizer efficiency.
Defects of bulk blending fertilizer
BB fertilizer has various varieties and different raw materials, resulting in different physical and chemical properties of BB fertilizer, such as uneven particle size and short storage time of products. Different chemical reactions occur between the materials of mixed fertilizer, which makes some finished products easy to dissolve or even become mud in packaging bags, thus affecting fertilizer efficiency.
