The invention discloses a preparation technology of zeolite nitrate fertilizer and belongs to the fertilizer industry. The preparation technology comprises the following steps of: carrying out neutralization reaction, evaporating and dehydrating, stirring and mixing, pelletizing and packaging separately. According to the preparation technology disclosed by the invention, the design is novel, the process is advanced, the method is special and the use is extensive. By adopting the preparation technology, not only the nitrate fertilizer loss problem with the water is solved, but also the release supply time of the nitrate fertilizer in the soil and the water is prolonged. Meanwhile, the operation is easy, the production cost is low, and the practicability and the generalization performance are great.
Description
Technical field [0001] The invention relates to a preparation technology of nitrate zeolite fertilizer, which belongs to the fertilizer industry. Background technique [0002] At present, nitric acid fertilizer is applied to the soil with the disadvantage of water loss. Summary of the invention [0003] The invention provides a preparation technology of nitrate zeolite fertilizer, which can overcome the above-mentioned drawbacks. [0004] The present invention is realized by adopting the following technical scheme: A preparation technology of nitrate zeolite fertilizer, which includes neutralization reaction, evaporation and dehydration, stirring and mixing, granulation, and sub-packaging. It is characterized by: nitrate zeolite fertilizer preparation technology, which is Add 5-85% calcium nitrate tetrahydrate solution into a stainless steel neutralization reaction tank with a diameter of 4000×3000mm, and then add 3-8% ammonium nitrate solution to react to produce calcium ammonium ...
