Slow-release fertilizer equipment Henan Viet slow release fertilizer equipment development, and manufacturing equipment so-called slow-release fertilizers slow release fertilizer, refers to it through various regulatory mechanisms of nutrient initially slow release, extended crop nutrient absorption and effective use of its validity , the new pellet mill to nutrient release rate and release period in accordance with the set of slow or controlled release fertilizer. This fertilizer with improved fertilizer efficiency, reduce use and the number of fertilizer, reduce production costs, reduce environmental pollution, improve crop quality, etc., prominent feature is its release rate and release of the growth pattern of the combination of crops, fertilizer The new pellet mill, so that the effective utilization of fertilizers increased by 30%. Slow-release fertilizer in the traditional fertilizer outer package layer of special film, based on crop nutrient demand, controlled release nutrient release rate and release, the nutrient release profile is consistent with the crop requirements. The outstanding feature is the synchronization of fertilizer supply in accordance with the law of crop growth curve available nutrients, so that the effective utilization of fertilizer nutrients has been greatly improved, in ensuring the premise of crop growth, compared with the same concentration of fertilizer, fertilizer utilization can be increased by 30% , can greatly reduce the amount of conventional fertilizer. Because of slow-release fertilizer with a reduced amount of fertilizer, saving fertilizer raw materials (coal, electricity, natural gas), improve fertilizer use efficiency, reduce environmental pollution, etc., it is called the "21st century high-tech green manure" as the fertilizer industry direction of development. Resolve conflicts fertilization usually takes dressing, but if you do not combine dressing time losses and waste of irrigation, fertilizer is great. Slow-release fertilizer to achieve a fertilization, without dressing it with a release of a long-term role in the new inorganic fertilizer pellet mill, can greatly improve the fertilizer, reducing fertilizer and reduce costs. Ammonium nitrate fertilizer Ammonium nitrate fertilizer equipment Henan Viet equipment manufactured ammonium nitrate fertilizer equipment and method of neutralization reaction can be carried out at atmospheric pressure, pressure or vacuum conditions. If inexpensive source of steam, and atmospheric pressure can be used to save equipment investment, simplify operations. Pressure and heat of reaction can be recovered, byproduct steam, used to preheat the feed and concentrated ammonium nitrate solution. When ammonia and nitric acid concentration of 64%, ammonia by-product steam per ton of about 1t. The use of a vacuum and is a combination of crystalline ammonium nitrate production, its equipment and the production of saturated ammonium sulfate crystallizer similar. Then granulated using different methods. Spray granulation tower is the most widely used ammonium nitrate granulation method. There are two kinds of ammonium nitrate and law and transformation of production methods. Transformation is the use of nitrate fertilizer production process byproduct calcium nitrate tetrahydrate material, ammonium carbonate solution reaction, generating ammonium nitrate and calcium carbonate precipitation, filtration, and the filtrate processed into ammonium nitrate fertilizer product or return the production system.
