【発明の詳細な説明】 ［発明の分野］ 本発明は、有機物を含有している化成肥料の製造方法に
関する。Description: FIELD OF THE INVENTION The present invention relates to a method for producing a chemical fertilizer containing an organic substance.

料が望まれる。BACKGROUND OF THE INVENTION In recent years, in order to enhance the functionality of fertilizers, compounding fertilizers with organic substances has been carried out. Recently, there has been a demand for a chemical fertilizer containing a higher proportion of organic substances, for example, containing 30% by weight or more of organic substances. On the other hand, because of the need for labor saving and cost reduction in agricultural work, side fertilization, mechanical fertilization such as power spraying is becoming widespread, and the fluidity suitable for the mechanical fertilization is high, and the particle hardness that does not easily powder is used. A fertilizer to have is desired.
有機物を含有する化成肥料は、一般に有機物と無機系化

系化成肥料成分の塩（以下、肥料塩と略記することがあ

末）を相互に付着させた後、転動造粒機で造粒すること
により製造されている。An organic matter-containing chemical fertilizer is generally prepared by mixing an appropriate amount of an organic matter and an inorganic chemical fertilizer, and further using a mixer, an aqueous solution of water or a salt of an inorganic chemical fertilizer component (hereinafter sometimes abbreviated as a fertilizer salt). It is manufactured by adding the aqueous medium of (1), adhering the granules (fertilizer powder) to each other, and then granulating with a tumbling granulator.

水性媒体による肥料成分粘着作用が増大する。そして、
上記増大した粘着作用により、化成肥料粉末が有機物を
取り込みながら相互に結合して、粒状化が進行する。In the above method, water or fertilizer salt aqueous solution, by dissolving a part of the inorganic chemical conversion fertilizer components during rolling granulation,
The adhesive action of the fertilizer component by the aqueous medium is increased. And
Due to the increased adhesive action, the chemical fertilizer powder binds with each other while taking in the organic matter, and the granulation proceeds.

が困難になったり、得られた造粒物の粒子硬度が低下
し、あるいは、造粒後の乾燥または機械施肥の際に粉化
しやすくなるという問題がある。However, the amount of organic substances added increased, for example,
When the content is more than about 10% by weight, the amount of the inorganic chemical fertilizer component is relatively decreased, so that the tackiness of the aqueous medium obtained by dissolving the inorganic chemical fertilizer component may not be sufficiently obtained. If the tackiness of the aqueous medium is insufficient, the granulation itself becomes difficult, or the particle hardness of the obtained granules decreases, or powdered during drying or mechanical fertilization after granulation. There is a problem that it becomes easier.

は、圧縮ロール、ブリケッティングロール、ペレタイザ
ーなどを用いて圧縮成形する方法が知られているが、圧
縮成形によって得られた粒子は、通常ペレット状である
ために流動性が低く、機械施肥が実施しにくい。As a method of granulating a fertilizer with a high organic compounding ratio, a method of compression molding using a compression roll, a briquetting roll, a pelletizer, etc. is known, but the particles obtained by compression molding are usually pellets. Since it is in a shape, it has low fluidity and is difficult to apply by mechanical fertilization.
なお、本明細書において、「粒状」とは、球状もしくは
球状に近く実質的に角ばった部分がない形状を意味し、
「ペレット状」とは、円盤状、円柱状、もしくは凸レン
ズ状であって角ばった部分が有ってもよい形状を意味す
る。In the present specification, the term "granular" means a spherical shape or a shape that is substantially spherical and has substantially no angular portion,
The “pellet shape” means a disk shape, a column shape, or a convex lens shape that may have angular portions.

大きな粒子が多くなる傾向がある。Therefore, it has been proposed to add a viscous liquid such as an aqueous polyvinyl alcohol solution, a lignin liquid, or a molasses liquid to a fertilizer containing a large amount of organic matter, and perform rolling granulation using the liquid as a medium. . Rolling granulation is possible by using the above liquid as a medium, but when polyvinyl alcohol aqueous solution is used, the cost of fertilizer production increases because the polyvinyl alcohol itself is expensive compared to the fertilizer raw material, and lignin is used. When liquid or molasses liquid is used, the particle hardness increases to a certain degree, but a large amount of inorganic substances are adhered and bound for granulation, resulting in a decrease in the content of organic substances in the granulated product or a wide particle size distribution. There is a tendency that the number of relatively large particles increases.

Particles that passed through the mesh sieve and remained on the 12 mesh sieve (hereinafter abbreviated as 5 to 12 mesh) were obtained as organic matter-containing granular fertilizer. The organic matter content of the fertilizer was calculated by chemical analysis of each of the inorganic N-P-K and the organic N-P-K in the fertilizer, and the ratio of the analysis values of both.
Further, the dried granules are sieved using a Tyler standard sieve, and 20 granules are arbitrarily taken out from the granules obtained as a residue of the 7-mesh sieve, which is a passing portion of the 5-mesh sieve, The hardness was measured using a Kiya type hardness meter, and the average value was defined as the average particle hardness of the organic matter-containing granular fertilizer.
