BB fertilizer is different from the organic fertilizer and chemical fertilizer, the name of BB fertilizer comes from English Bulk Blending Fertilizer, also known as blending fertilizer, which is made by blending elemental fertilizer (or multi-fertilizer) in a certain proportion. It is a compound fertilizer in which several granular single fertilizers or compound fertilizers are blended in a certain proportion.

  The total requirement of the mixed fertilizer for blending fertilizer is uniform particle size, low moisture content, good particle strength, no agglomeration during storage, raw fertilizer for blending fertilizer, consistency of particle size, not only the upper and lower limits of particle size are consistent and they are required to have a similar granular distribution. Therefore, analysis of the particle size distribution of different raw materials before the fertilizer is blended is an important step to ensure the quality of the blended fertilizer.


  The advantages of the fertilizer are:
  1. The comprehensive concentration of nutrients is high, the yield is increased, the cost is significant, and the pertinence is strong. The nutrient-to-distribution ratio of BB special fertilizer is based on the characteristics of crop fertilizer requirements, and is based on the local soil nutrient supply status, which is both scientific and targeted.
  2. Simple processing, low production cost and no pollution.
  3. Flexible formula. It can be flexibly changed according to different conditions such as crop nutrition, soil fertility and yield level, which makes up for the shortcomings of general general-purpose compound fertilizer which is easy to cause a certain nutrient deficiency or excess due to the fixed nutrient distribution ratio.
 
  The equipment of BB fertilizer mixer is novel and practical. It is mainly composed of lifting feeding system, high-precision mixing system, storage system frame and electronic control system. It can be self-flowing and continuous production.
