The present invention relates to a method for producing granular dissolved phosphorus fertilizer. In recent years, with the modernization of agriculture, a method of mechanically distributing a bulk blend of several types of fertilizers has been used to save labor in fertilization, but this method is only intended for granular fertilizers. Classification is difficult and cannot be applied to so-called fine grain fertilizers such as dissolved phosphorous fertilizers. Therefore, several methods of granulating melted phosphorous fertilizer have been attempted, and various binders have been proposed. For example, granulation using pulp waste liquid, granulation using mixed waste liquid and bentonite, urea, nitrofumic acid,
There are methods that use the solid content of alcohol fermentation waste liquid and methods that use bentonite. By the way, dissolved phosphorous fertilizer is almost insoluble in water, so it is considered an essential condition for granular dissolved phosphorous fertilizer to quickly disintegrate into its original fine particles after application, but on the other hand, its transport, Granules are required that have sufficient strength to withstand storage, have an appropriate apparent specific gravity, do not generate dust, and have a good texture. Conventionally, various methods of granulating powdered dissolved phosphorus fertilizers for this purpose have been known as described above, but the present inventors first developed a method for granulating them using mainly organic by-products such as alcoholic fermentation waste liquid as a binder. (Japanese Unexamined Patent Publication No. 149885/1985). However, when granulation is performed using such by-products, the production volume of the main product tends to be controlled, so not only is the supply not stable, but the quality is also likely to vary. In addition, by-products such as alcohol fermentation waste have a strong odor and decay, leading to BOD.
Due to its high content, it not only worsens the working environment but also has disadvantages such as the cost of removing BOD. In view of the above problems, the present inventors conducted research to obtain a granulated product that is more industrially advantageous, and surprisingly discovered that magnesium sulfate is an excellent binder, and completed the present invention. . That is, the present invention provides a method for producing granular melted phosphorous fertilizer comprising melted phosphorous fertilizer powder and a binder, in which the specific surface area is
100 parts by weight of 10 to 60% by weight fine powder dissolved phosphorous fertilizer with a particle size of 44μ or less and 1 to 7 parts by weight of magnesium sulfate as a binder (MgSO 4
Add appropriate amount of water to the mixture (converted) and granulate it,
The present invention relates to a method for producing a granular melted phosphorus fertilizer that disintegrates quickly after application, and is characterized by drying at ~120°C. The melted phosphorus fertilizer applied in the present invention is no different from that commonly used, and is a mixture of phosphate rock and magnesium silicate minerals such as serpentine, peridotite, or smelted nickel in a predetermined ratio. It is a glass-like powder obtained by heating and melting it, then rapidly cooling it with water, etc., and pulverizing it. In this case, trace elements such as boron, manganese, copper, zinc, or molybdenum may be present in the melted phosphorous fertilizer as necessary. The particle size and specific surface area of the dissolved phosphorus fertilizer, together with the properties of the binder used, significantly affect the physical properties when granulated, so it is necessary to adjust them within a predetermined range. The surface area is 500 to 3000cm 2 /g, and the particle size is 44μ or less.
A content of 10 to 60% is most preferable; outside this range, it tends to be difficult to satisfy the requirement for properties in which water disintegration and granulation strength are mutually contradictory. Next, in the present invention, a substance containing magnesium sulfate is used as a binder in granulating the powdered dissolved phosphorus fertilizer, which is not only industrial magnesium sulfate but also a combination of magnesium hydroxide and sulfuric acid. It also includes reaction products, reaction products of magnesia and sulfuric acid, reaction products of serpentine or peridotite and sulfuric acid, etc., and is mainly composed of MgSO 4 but also contains some MgCl 2 , It may contain Mg(OH) 2 . Therefore, even if a certain amount of unreacted magnesium etc. is mixed in due to its nature, it can be used without any problem as long as it substantially contains magnesium sulfate. It may be of. The amount of magnesium sulfate-containing substances used in powdered dissolved phosphorous fertilizer varies depending on manufacturing conditions and the physical properties of the contained material, but in most cases it is 1 to 7 as MgSO 4 per 100 parts by weight of dissolved phosphorous fertilizer. parts by weight, preferably 2
A range of 4 parts by weight is suitable. The reason for this is that if it is less than 1 part by weight, granulation becomes difficult, while if it is more than 7 parts by weight, it is not only uneconomical but also causes problems in terms of balance with the fertilizing ingredients. The granular dissolved phosphorous fertilizer according to the present invention is obtained by granulating and drying a specific blend of the fine powder dissolved phosphorous fertilizer and a substance containing magnesium sulfate as described above at a temperature of 70 to 120°C. In other words, in order to granulate granular dissolved phosphorus fertilizer using a substance containing magnesium sulfate, conventional granulation methods can be used without particular limitation, such as a dish granulator, a drum granulator, or a compression molding machine (press granulator). ), etc., to granulate it while adding an appropriate amount of water, and then dry it at a temperature of 70 to 120°C until it becomes a substantially dehydrated product, and if necessary, classify it to form a product. do. If the drying conditions are not as described above, not only will it not be possible to obtain a granulated product having the following predetermined particle size with a good yield, but also the granulated product will not have the strength to withstand storage and transportation of the granulated product. The size of granules is not uniform depending on the purpose, but
In most cases, a range of 0.5 to 5 mm, preferably 1 to 4 mm is appropriate, and those outside this range are returned to the initial step and reused. Thus, according to the present invention, soluble magnesium and sulfuric acid roots are added to dissolved phosphorus fertilizer, which has conventionally been difficult to make into granules, to form particles of a desired size, which are then blended with other fertilizers and mechanically distributed. Furthermore, it is possible to provide a granulated dissolved phosphorus fertilizer which has good water disintegration properties and soil disintegration properties. Furthermore, it has appropriate strength, apparent specific gravity, and good texture with no dust generation, and is more compliant with the Offensive Odor Prevention Law, Water Pollution Prevention Law, Soil Pollution Prevention Law, Industrial Hygiene Law, etc. compared to granulated products that use organic matter as a binder. The present invention has great industrial significance because it can be manufactured without causing any problems in compliance with the various laws and regulations, and can be handled safely in use. Hereinafter, the present invention will be specifically described with reference to Examples. Examples 1 to 6 A mixture prepared by adding a predetermined amount of a magnesium sulfate-containing substance to the powdered dissolved phosphorous fertilizer shown in Table 1 was prepared using a dish-type granulator (diameter 800 mm, depth 100 mm, rotation speed 12 r.pm, inclination angle
52°) and spray with water until the particle size is 1 to 4 mm.
(preferably 2 to 3 mm). Dry this (70 to 120°C) to reduce the moisture content to 0.1% or less.
After cooling, this material was sized to a particle size of 1 to 4 m/m, and this ratio was taken as the yield rate to obtain a melted phosphorus fertilizer granule. Regarding this product, average crushing strength, water disintegration,
Table 1 shows the test results of soil disintegration and chemical analysis values using the official fertilizer analysis method.
