Fertilizer types suitable for the production of compound fertilizer granulators
The compound fertilizer granulator is a key equipment in the production process of compound fertilizers. By processing materials to form granular fertilizers with certain particle size, strength, and shape, it can produce various types of fertilizers, as follows:
Chemical synthesis compound fertilizer: Chemical synthesis compound fertilizer is made through chemical reactions and has a relatively fixed composition. Taking diammonium phosphate as an example, the granulator neutralizes raw materials such as phosphoric acid and liquid ammonia at a specific temperature and pressure. The resulting material is processed by the granulator to form diammonium phosphate products with uniform particles and stable nutrient content. This type of compound fertilizer has the advantages of high nutrient content, low side components, and good physical properties, which can meet the diverse nutrient requirements of crops at different growth stages.
Mixed compound fertilizer: Mixed compound fertilizer is a mixture of two or more elemental fertilizers or compound fertilizers with similar particle sizes in a certain proportion. In the production process, simple fertilizers such as urea, superphosphate, and potassium chloride are crushed separately, mixed according to the formula ratio, and then granulated by a granulator to make a mixed compound fertilizer. This fertilizer can flexibly adjust the nutrient ratio according to soil conditions and crop needs, and has the characteristic of flexible formula.
Blended compound fertilizer: Blended compound fertilizer, also known as BB fertilizer, is a type of compound fertilizer made by blending several granular single fertilizers in a certain proportion. The granulator will pre produce granular fertilizers with different particle sizes and nutrients, such as large urea particles, potassium dihydrogen phosphate particles, etc., and accurately measure and evenly mix them according to the formula requirements to form a blended compound. Its advantage is that the production process is simple, and the formula can be quickly adjusted according to market demand and changes in crop planting structure to meet the fertilization needs of different regions and crops.
Organic inorganic compound fertilizer: Organic inorganic compound fertilizer is made by mixing and granulating organic fertilizer and inorganic fertilizer in a certain proportion. Using a granulator, organic materials such as livestock manure and crop straw that have been fermented are thoroughly mixed with inorganic fertilizers such as urea and potassium sulfate, and then processed into granules through granulation technology. This fertilizer contains both organic matter and quick acting nutrients, which can improve soil structure, enhance soil fertility, and provide comprehensive nutrients for crops.
Slow release/controlled release compound fertilizer: Slow release/controlled release compound fertilizer uses a special granulation process to slowly release fertilizer nutrients and prolong fertilizer efficiency. During the production process, the granulator coats the surface of ordinary compound fertilizer particles with materials such as resin and sulfur, forming a semi permeable film to control the release rate of nutrients; Alternatively, special additives can be added during the granulation process to alter the physical and chemical properties of the fertilizer, achieving slow-release or controlled release of nutrients. This type of fertilizer can reduce the frequency of fertilization, improve fertilizer utilization efficiency, and reduce environmental pollution.
The above introduces the common types of fertilizers suitable for the production of compound fertilizer granulators. If you still want to know the production process of a certain type of fertilizer or detailed information about a specific granulator, we will continue to answer your questions.
