Segregation problems in bulk blended fertilizers organic fertilizer equipment

2022/09/29

 Small scale bio organic fertilizer production equipment bulk blended fertilizer segregation: Bulk blended fertilizer may cause uneven distribution of nutrients in the fertilizer, resulting in unreasonable nutrient supply after application to the soil. This phenomenon is called "segregation". "Nutrient segregation" is not closely related to the density and size of fertilizers, mainly because the particle size distribution ratio of different fertilizer raw materials is too different. Practice has proved that the consistency of particle size of raw material fertilizers used for blended fertilizers requires not only the same upper and lower limit values ​​of particle size, but also similar particle size distributions. A difference of no more than plus or minus 10% is acceptable.
Basic requirements of organic fertilizer npk production line: The general requirements of blended fertilizers for basic fertilizers are uniform particle size, low moisture content, good particle strength, and no agglomeration during storage. The granules and large crystals obtained by spray granulation can be pressed into tablets, and the irregular granules obtained by crushing and sieving can also be used, but certain requirements must be met. In addition, the most effective form of nutrient release from different fertilizers should also be considered. For example, some nitrogen fertilizers are generally easy to fall into water. When the particles are large, the dissolution rate of nitrogen can be reduced, which is beneficial to the absorption and utilization of crops.

The roller extrusion granulator is the key equipment for compound fertilizer granulation. It has advanced technology, reasonable design, compact structure, novel and practical, low energy consumption, and is matched with corresponding equipment to form an npk production fertilizer line, which can form a certain continuous production. , Mechanized production, no drying, room temperature production, product rolling molding ability, product quality meets the technical requirements of compound fertilizer, is the latest product of high, medium and low concentration special compound fertilizer, compound fertilizer industry to save energy and reduce consumption.
