Description
【発明の詳細な説明】 〔産業上の利用分野〕 この発明は、粗骨肥料基材の粒状化方法に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a method for granulating a coarse bone fertilizer base material.
近年、農業事情を取り巻く環境は厳しく、肥料業界もそ
の影響により、農作業の省力化、生産費の節減を図る目
的から粒状肥料の要請が多くなっている。In recent years, the environment surrounding agriculture has been severe, and the fertilizer industry has been affected by this, with an increasing number of requests for granular fertilizers for the purpose of saving labor in farming and reducing production costs.
従来、粗骨肥料基材の粒状化については、主として粉砕
を容易にし製品の圧密炭を上げる目的から、第1図に示
すように、まず基材を粗砕して乾燥してから粉砕する。Conventionally, with regard to granulation of coarse bone fertilizer base material, the base material is first coarsely crushed, dried, and then crushed, as shown in FIG. 1, mainly for the purpose of facilitating crushing and producing compacted coal as a product.
そしてこれに肥料成分を補完する副資材と、造粒に必要
な結合材とを混入し、混練して造粒したものを分級し、
乾燥して製品化する方法が採用されていた。Then, auxiliary materials that complement the fertilizer components and binding materials necessary for granulation are mixed in, kneaded, and granulated, which is then classified.
The method used was to dry and commercialize the product.

れるために最近注目されているので、特に造粒化の要請
が強い。In addition, examples of the coarse bone fertilizer base material include fossil shells, discarded shells of shells, animal bones, rocks for fertilizers, raw materials on seedling beds, and the like. Among these, shellfish fossils are mainly produced in Hokuriku, Hokkaido, Iyu, and Tohoku. Traditionally, they have been dried and powdered and used as fertilizer, but they dissolve and react slowly in the soil, reducing soil acidity. Recently, it has been attracting attention due to its excellent functions such as long-term correction and promoting the absorption of major nutrients such as nitrogen, phosphoric acid, and potassium in crops, so there is a strong demand for its granulation.
従来の粗骨肥料基材の粒状化方法によれば、上述の如く
、基材をまず粉体にする工程を経てから造粒工程に移行
するために種々の問題があった。According to the conventional method of granulating a coarse bone fertilizer base material, as mentioned above, there are various problems because the base material is first pulverized through a process and then transferred to a granulation process.
すなわち、基材から粉体(粉末、微粉)を得るには、殊

要であり、それには広い土地、熱エネルギー、労働力等
が必要とされ、時には公害の補償の問題も生じてくるこ
とから、製品がどうしてもコスト高となることは避けら
れなかった。That is, in order to obtain powder (powder, fine powder) from a base material, especially if the base material has a high moisture content, drying and pulverization processes are necessary, which requires a large amount of land, thermal energy, labor, etc. Because of the necessity and sometimes the problem of compensation for pollution, it was inevitable that the product would be expensive.
加えて、乾燥・粉砕調整された原料に副資材や粒状化促

塞現象の防止対策、補修費、労務費を必要とし、併せて
各設備間の連続化輸送機器が必要である。In addition, a kneading process is required to measure and mix auxiliary materials and granulation promoters into the dried and pulverized raw materials, but this also requires land, capital investment, energy, and noise associated with equipment installation. In addition, when the granulation accelerator is a liquid, water heats up due to friction, and this is the main cause, requiring preventive measures and repair costs for exhaust guidance equipment and exhaust guidance system passages. , labor costs are required, and continuous transportation equipment between each facility is also required.
また、混練された原料は造粒機(パン造粒の場合は連続
運転)へ輸送されるが、輸送量が一定でないとパン内の
運動が崩れ、不良品が排出される。In addition, the kneaded raw materials are transported to a granulator (continuous operation in the case of bread granulation), but if the amount of transport is not constant, the movement within the bread will be disrupted and defective products will be discharged.
また、水スプレ位置、スプレ量の監視が必要であった。Additionally, it was necessary to monitor the water spray position and amount.
この発明は、上記のような実情に鑑みて、造粒が合理的
になされるために、その前工程として乾燥と粉砕の工程
を省略でき、一つのパン内において混合・粉砕・造粒の
工程を一挙になし得る貝化石等の粗管肥料基材の粒状化
方法を提供することを目的としたものである。In view of the above-mentioned circumstances, this invention enables granulation to be performed rationally, so that the drying and pulverizing steps can be omitted as pre-processes, and the mixing, pulverizing, and granulating steps can be performed in one pan. The purpose of this invention is to provide a method for granulating coarse tube fertilizer base materials such as shellfish fossils, which can accomplish the following in one step.
上記の目的を達成するためのこの発明の構成は。 The structure of this invention is to achieve the above object.
基材を粗砕する工程の次に、乾燥と粉砕の工程を省略し
、粗砕した基材をパン内に副資材と結合材と共に混入し
、パン内において逆流式高速混合により混合・粉砕・造
粒することをその要旨とする。Next to the step of coarsely crushing the base material, the drying and crushing steps are omitted, and the coarsely crushed base material is mixed into a pan together with auxiliary materials and binding materials, and then mixed, crushed, and mixed by high-speed backflow mixing in the pan. The gist is to granulate.

燥がなされていなくても、所望の形態に粉砕や造粒が可
能であり、基材に含まれていた水分が却って造粒のため
に利用されるため、造粒中に水の供給が不要であり、必
要としても僅少で足りる。According to the above configuration, the base material is simply crushed and put into a pan together with auxiliary materials and binding materials, and is immediately crushed in the pan, but since the crushing is performed by powerful backflow high-speed mixing, drying is not performed. It is possible to crush and granulate into the desired form even without water, and since the water contained in the base material is instead used for granulation, there is no need to supply water during granulation. However, a small amount is enough.

心して設けられた撹拌工具がパンと逆方向に回転するの
で、基材が強力に破砕して粉体化される。また、工具の
形状によっては原料が躍動し、躍動により互いに摩擦し
ながら粒状化する。In the backflow type high-speed mixing, a stirring tool installed eccentrically with respect to the center of the pan rotates in the opposite direction to the pan, so that the base material is strongly crushed and powdered. Also, depending on the shape of the tool, the raw materials move, and the movement causes them to rub against each other and become granulated.
副資材の混入は製造目的の製品により計算値子αの添加

粒状品が要望されるが、嵩比重の小さいものを副資材と
して添加すればその要望に応えることができる。The mixing of auxiliary materials may be done by adding a calculated value α depending on the product to be manufactured. In addition, there is a water disintegration test for fertilizers, and for this test, a chloride-based dispersion promoter with a 1.0
It is sufficient to add around %. In recent years, there has been a demand for lightweight granular products for use on seedling beds, and this demand can be met by adding products with low bulk specific gravity as auxiliary materials.
粒状化促進材については、対象作物或は使用目的により
粉体または液体のものを選択的に添加する。粉体と液体
とのいずれの場合も、基材に対して1.5%以内の添加
量で足りる。Regarding the granulation accelerator, powder or liquid is selectively added depending on the target crop or purpose of use. In both cases of powder and liquid, it is sufficient to add the amount within 1.5% based on the base material.
また、最近ではゴルフ場向けの目上として着色粒状品が

Chloride apron 1.5 The shell fossils are coarsely crushed by passing them between rollers. However, this may also be done by other means, such as by hitting with a hammer. The thus coarsely crushed material is weighed together with auxiliary materials, binders, and dispersion promoters, and then transferred to the next step, a backflow type high-speed mixing step. In this process, an apparatus (hereinafter simply referred to as the mixer) called the Eirich backflow type high speed mixer (manufactured by Eirich Co., Ltd., Germany, sold by Eirich Japan Co., Ltd.) was used.

再び混合領域に戻される。This mixer is based on the backflow principle, in which a pan 1 containing raw materials rotates clockwise, and a mixing blade 3 of a stirring tool 2 mounted eccentrically with respect to the center of the pan has a rake angle. Since the stirring tool 2 rotates relatively in a circular orbit inside the pan 1 while throwing up the raw material, horizontal and vertical flows occur evenly in the raw material. Further, the raw materials around the pan 1 are returned to the mixing area by a fixed scraper.
このような機構に加えて、高速アジテータ5を導入でき

、粒子がほぼ均一で密度が高いことである。In addition to such a mechanism, a high speed agitator 5 can be introduced. This high-speed agitator 5 is installed in the pan 1 and rotates at high speed to exert impact and friction effects. Further, by setting the rotation speed, processing conditions, etc., a granulation effect can be imparted. The characteristics of this granulation are that the particles are almost uniform and dense.

によれば1次のような利点がある。As described above, this mixer is suitable for processing various raw materials, and has multiple functions such as homogenization, kneading, pulverization, loosening activation, humidity control, and granulation. The reason why this excellent function can be demonstrated is that the normal input power is 1 to 4 KW/100 Q.
10~29KW/10 due to unique tool selection
This is because it is possible to increase the temperature to 0 Q and achieve strong mixing. The advantage of intensive mixing is that the throughput per unit equipment cost or installation area is large. Furthermore, this mixer has the following advantages.
1)装置において工具の調整によりライナー、スフレバ
ーの摩耗が小さい。1) Wear of the liner and souffle bar is reduced by adjusting the tools in the equipment.
2)パン内は高速回転により打撃・摩擦作用により飛散
・流動し位置変換が活発であることから混合効果が向上

6)補修費も僅少で済む。6) Repair costs are also minimal.
そこで、混合機に粗砕された貝化石を副資材と結合材と
共に投入すると、混合・粉砕・造粒が行われるので、次
にパン1から排出した粒状の貝化石肥料を乾燥し、分級
することによって製品化する。Therefore, when the coarsely crushed shellfish fossils are put into the mixer together with auxiliary materials and binding materials, mixing, crushing, and granulation are performed.Then, the granular shellfish fossil fertilizer discharged from pan 1 is dried and classified. commercialize it by doing so.
混合機においては、バッチ方式のため、条件設定により
最良の運転状態が得られ、不良粒状品の排出がない。し

布のための作業員を必要としたが、その作業員は不要と
なる。Since the mixer is a batch system, the best operating conditions can be obtained by setting the conditions, and there is no discharge of defective granules. Moreover, fossil shells contain 10 to 20% water, but this is used as is for the water required for granulation, so there is no need to replenish water during granulation, and even if it is necessary, only a small amount is sufficient. Regarding this point, the dish-type granulation method required a worker to spray water, but that worker is no longer required.
また、従来の造粒機には危険防止対策が必要であるが、
この混合機によれば、パンが密閉して運転されるため、
何ら危険がないことは勿論、騒音も少く原材料が飛散す
る不都合もない。In addition, conventional granulators require safety measures, but
According to this mixer, the bread is operated in a sealed manner, so
Of course, there is no danger, there is little noise, and there is no inconvenience of raw materials scattering.
以上説明したように、基材を粗砕する工程の次に、造粒
工程に至るまでの前処理としての乾燥と粉砕の工程が省
かれるため、乾燥や粉砕のための土地、設備投資、エネ
ルギー、補修費、監視要員が不要となり、乾燥は造粒後

の省略は、原料中の水分を造粒に寄与させる結果となる
ため、粗管肥料基材の粒状化について巧みにコストダウ
ンを計り得たという優れた効果がある。As explained above, after the process of coarsely crushing the base material, the drying and crushing process as a pretreatment before the granulation process is omitted, so there is no need for land, equipment investment, or energy for drying or crushing. , repair costs and monitoring personnel are not required, and drying is a relatively simple process after granulation, and omitting drying before granulation causes moisture in the raw materials to contribute to granulation, resulting in coarse grains. This has the excellent effect of skillfully reducing the cost of granulating the tube fertilizer base material.
加えて騒音や危険が少なく安全且つ良好な環境で操業が
可能となるという効果もある。In addition, there is also the effect that operations can be performed in a safe and favorable environment with less noise and danger.
