〔産業上の利用分野〕
本発明は、植物の栄養に供すること、または、
植物の栽培に資するために使用する化成肥料の製
造方法に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to providing nutrition to plants, or
The present invention relates to a method for producing a chemical fertilizer used for cultivating plants.
肥料は、農業にとつて不可欠の基礎資材であ
り、窒素、リン酸、加里に代表される肥料成分
は、目的により種々の配合で混合されるので非常
にその種類が多い。
Fertilizer is an indispensable basic material for agriculture, and there are many types of fertilizer components, such as nitrogen, phosphoric acid, and potassium, which are mixed in various formulations depending on the purpose.
また、流通時における偏析、施肥時の飛散を防
止するため造粒したものは、化成肥料という名称
で他の肥料と区別している。 In addition, granulated fertilizers to prevent segregation during distribution and scattering during fertilizer application are distinguished from other fertilizers by the name chemical fertilizers.

後、円筒型回転乾燥機で乾燥し、篩分けし、一般
には１〜５mmのサイズのものを袋詰めして製品と
する。篩分けの際発生するオーバーサイズとアン
ダーサイズは原料へリターンして再使用する。 The manufacturing method is to mix several types of salt powder containing fertilizer ingredients in a predetermined amount, then add and mix bentonite, carboxymethylcellulose, or lignin sulfonate as a binder, and add water in a spray form. After granulation using a dish-type rotary granulator or a cylindrical rotary granulator, it is dried in a cylindrical rotary dryer, sieved, and generally packed into bags with a size of 1 to 5 mm. and make it into a product. Oversize and undersize generated during sieving are returned to raw materials and reused.
このような工程のなかで、水を加えて造粒する
際、肥料成分がイオン化して水に溶解するため、
ベントナイトは、バインダー機能である膨潤性が
阻害され、カルボキシルメチルセルローズおよび
リグニンスルホン酸塩も溶解したイオン、例えば
NH4 +K+PO4 3-と反応し、増粘せずバインダー機
能を妨げられる。 During this process, when water is added and granulated, the fertilizer components are ionized and dissolved in the water.
Bentonite has its binder function, swelling properties, inhibited, and also contains dissolved ions such as carboxymethyl cellulose and lignin sulfonate.
Reacts with NH 4 + K + PO 4 3- and prevents binder function without thickening.
従つて、溶解速度の速い原料を使用する配合の
ものほど造粒しにくく、造粒収率が極めて低く、
60％未満の収率での製造を余儀なくされているの
が現状であり、また、はなはだしくは造粒したく
ても不可能なため、混合した粉末のまま流通して
いる肥料もあり、各メーカーは、造粒技術の研究
を重ね問題点の克服に努めているのが現状であ
る。 Therefore, formulations that use raw materials with a faster dissolution rate are more difficult to granulate and have extremely low granulation yields.
Currently, we are forced to manufacture fertilizers with a yield of less than 60%, and even if we wanted to granulate it, it was impossible, so some fertilizers are distributed as mixed powders, and each manufacturer Currently, the company is making efforts to overcome the problems through repeated research on granulation technology.
本発明は、化成肥料の造粒バインダーにホルマ
イト系鉱物を使用することにより、造粒が非常に
困難で造粒収率の低い配合のものであつても、高
収率で容易に造粒が可能になり、従来、造粒が不
可能とされている配合のものでそれが可能になる
ことを知見し、本発明を完成させたものである。
The present invention uses formite-based minerals as a granulation binder for chemical fertilizers, making it possible to easily granulate with high yield even if the formulation is extremely difficult to granulate and has a low granulation yield. The present invention has been completed based on the discovery that granulation is now possible with a formulation that has conventionally been considered impossible.
即ち、第１発明は化成肥料原料粉末から化成肥
料を造粒するに際して、バインダーとして重量比
で、1.0〜15.0％のホルマイト系鉱物を添加し、
造粒収率を向上されるものであり、第２発明は、
第１発明に、ベントナイト、リグニンスルホン酸
塩、カルボキシルメチルセルロースのうち１種ま
たは２種以上を添加して、造粒収率向上のための
相乗効果を図つたものである。 That is, the first invention adds 1.0 to 15.0% by weight of a holmite mineral as a binder when granulating a chemical fertilizer from chemical fertilizer raw material powder,
The granulation yield is improved, and the second invention is
One or more of bentonite, lignin sulfonate, and carboxymethylcellulose are added to the first invention to achieve a synergistic effect for improving the granulation yield.
ここで、ホルマイト系鉱物が1.0％以下では造
粒促進の効果が少なく、その下限を1.0％とした。
また、15.0％を越えて添加すると粘性が高くな
り、造粒工程中での流動性が阻害され、収率が著
しく低下するためその上限を15.0％とした。 Here, if the holmite mineral content is 1.0% or less, the effect of promoting granulation is small, so the lower limit was set at 1.0%.
Furthermore, if it is added in an amount exceeding 15.0%, the viscosity increases, the fluidity during the granulation process is inhibited, and the yield is significantly reduced, so the upper limit was set at 15.0%.
ホルマイト系鉱物は、繊維状の結晶構造であ
り、水中に分散した場合、0.5〜3.0μｍの繊維長
とその約百分に１の繊維径を有し、この繊維のか
らみあいにより高い粘性、すなわち可塑性の富ん
だバインダーとなる。
Holmite minerals have a fibrous crystal structure, and when dispersed in water, they have a fiber length of 0.5 to 3.0 μm and a fiber diameter of about 1/100 of that, and the entanglement of these fibers results in high viscosity, that is, plasticity. It becomes a rich binder.
このホルマイト系鉱物を、造粒しようとする肥
料原料の粉末に、1.0〜15.0％を添加混合し、加
水しながら造粒すると、ホルマイト系鉱物の繊維
が湿潤状態になつた原料中に良く分散し、極めて
良好なバインダー効果を発揮する。 By adding 1.0 to 15.0% of this formite mineral to the powder of the fertilizer raw material to be granulated and granulating it while adding water, the fibers of the formite mineral will be well dispersed in the wet raw material. , exhibits an extremely good binder effect.
本発明のバインダー効果に寄与する粘性、即

起因するものではなく、物理的な繊維のからみあ
いによるものであるため、溶解したイオンの化学
的な影響をほとんど受けない。 The viscosity, or plasticity, that contributes to the binder effect of the present invention is not due to swelling action like bentonite, but is due to the physical entanglement of fibers, so it is almost immune to the chemical effects of dissolved ions. I don't accept it.
さらに、ホルマイト系鉱物は、リグニンスルホ
ン酸塩、カルボキシルメチルセルロース等有機質
繊維のように、溶解したイオンと反応してバイン
ダー機能を喪失するものでもなく、安定した無機
質繊維であるため、従来溶解したイオン、例えば
NH4 +K+PO4 3-等に影響されて造粒が非常に困難
なものでも大幅な収率向上が可能であり、また、
造粒不可能とされていたものでもその造粒が可能
になる。 Furthermore, unlike organic fibers such as lignin sulfonate and carboxymethyl cellulose, formite-based minerals do not react with dissolved ions and lose their binder function, and are stable inorganic fibers, so they are stable inorganic fibers that do not react with dissolved ions and lose their binder function. for example
It is possible to significantly improve the yield even for materials that are extremely difficult to granulate due to the influence of NH 4 + K + PO 4 3- , etc.
Even materials that were considered impossible to granulate can now be granulated.
さらには、ホルマイト系鉱物は、乾燥固結性に
優れているため、造粒後乾燥して製品になつた粒
硬度は従来品より向上し、流通、貯蔵中に破壊粉
化することもなく、農業の基礎資材である化成肥
料の製造方法に大きく貢献するものである。 Furthermore, since holmite minerals have excellent drying and caking properties, the hardness of the resulting products after granulation and drying is improved compared to conventional products, and they do not break down into powder during distribution or storage. This will greatly contribute to the production method of chemical fertilizers, which are basic agricultural materials.
