Abstract
The invention relates to the field of production equipment of fertilizers and particularly relates to an acid mixed nitrogenous fertilizer produced by adopting ammonium nitrate and ammonium sulfate as main materials and a preparation method thereof. According to the formula, the nitrogenous fertilizer comprises the following materials in percentage by weight: 50%-85% of ammonium nitrate, 50%-15% of ammonium sulfate, 0-10% of calcium-magnesium fertilizer, 0-5% of boron fertilizer, 0-5% of zinc fertilizer, 0-5% of iron fertilizer, 0-5% of manganese fertilizer, 0-5% of molybdenum fertilizer and 0-5% of copper fertilizer. The acid mixed nitrogenous fertilizer exists in a granular form or a powdery form. The production of the granular product comprises the steps of firstly, adding the ammonium sulfate, the calcium-magnesium fertilizer, the boron fertilizer, the zinc fertilizer, the iron fertilizer, the manganese fertilizer, the molybdenum fertilizer and the copper fertilizer into the ammonium nitrate in a fused state in proportion according to different crops to be applied with the fertilizer, then stirring uniformly, granulating by a high tower or in a form of spouting or by a rotary drum, cooling, adding anti-blocking powder or oil, and packaging to obtain the acid mixed nitrogenous fertilizer. The acid mixed nitrogenous fertilizer prepared by the method has the advantages that the safety problem of direct application of ammonium nitrate to agricultural production is solved, and the problem of single and low nitrogen content of ammonium sulfate directly used in agricultural production is solved.
Description
Technical field
The present invention relates to chemical fertilizers production equipment field, be specially a kind of ammonium sulfate that solved and be directly used in the single and problem on the low side of the nitrogen content of agriculture production, it is acid compound nitrogenous fertilizer of main material production and preparation method thereof that improvement soil is had to take ammonium nitrate and the ammonium sulfate of larger help.
background technology
Ammonium nitrate itself is a kind of high-quality instant nitrogenousfertilizer, because security reason is prohibited directly to use, all related productss all must be pressed WJ9050-2006 " agricultural ammonium nitrate capability of antidetonance test method and judgement " standard, and judgement possesses the capability of antidetonance could be in marketing.Due to production capacity surplus, produce the enterprise of ammonium nitrate all managing that ammonium nitrate is carried out to modification, enter agricultural market.
Ammonium sulfate is because the reason such as nitrogen content is on the low side is directly used in the few of agriculture production, and the ammonium sulfate of domestic production is now nearly all for balanced production, solves the by product of environmental issue, and using in a large number ammonium sulfate is also to have protected environment.
Present domestic saltings is many, and especially the Northwest such as Xinjiang, due to the life-time service of soil, may lack amount or trace element in some, need to add the required element of crop.
Summary of the invention
The present invention is just based on above technical problem, provide and can solve the safety problem that ammonium nitrate is directly used in agriculture production, solved ammonium sulfate and be directly used in the single and problem on the low side of the nitrogen content of agriculture production, improvement soil is had to larger help a kind of to take ammonium nitrate and ammonium sulfate be the acid compound nitrogenous fertilizer of main material production.
Another object of the present invention is to provide that a kind of to take ammonium nitrate and ammonium sulfate be the preparation method of the acid compound nitrogenous fertilizer of main material production.
Technical scheme of the present invention is:
The acid compound nitrogenous fertilizer that ammonium nitrate and ammonium sulfate are main material production, in quality percentage composition, the weight percent of its feed composition is:
Ammonium nitrate 50-85%
Ammonium sulfate 50-15%
Ca and mg fertilizer 0-10%
