（産業上の利用分野）
この発明は、粒状化促進材として苦土肥料又は石灰質肥
料を用いて造粒した粒状塩化カリ肥料に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a granulated potassium chloride fertilizer granulated using magnesia fertilizer or calcareous fertilizer as a granulation accelerator.
（従来の技術）
窒素、リン酸、カリ等の配合肥料において、カリ成分と
して塩化カリの結晶を使用する場合、塩化カリの結晶は
他の窒素、リン酸とは形状の大きさの違いから袋の下方
に溜ってしまい、開袋して施肥する場合、配合肥料のそ
れぞれの成分を均一に散布することか困難である。(Prior art) When using potassium chloride crystals as the potassium component in a compound fertilizer containing nitrogen, phosphoric acid, potassium, etc., the potassium chloride crystals are separated from other nitrogen and phosphoric acids in their shape and size. When fertilizer is applied by opening the bag, it is difficult to uniformly distribute each component of the compound fertilizer.
そこで、塩化カリを粒状にして配合する試みが行なわれ
ているか、塩化カリは造粒しにくい性質があり、単独で
は造粒することができない。Therefore, attempts have been made to mix potassium chloride in granular form, or else potassium chloride has a property of being difficult to granulate and cannot be granulated alone.
これに対して塩化カリの造粒性を向上させるために、粒
状化促進材として粉砕したシリコマンガン鉱滓１５重１
２％程度を混合し、これに結合剤とし゛てポリビニール
アルコール等を用いて造粒したものが知られている。On the other hand, in order to improve the granulation properties of potassium chloride, 15 pieces of crushed silicomanganese slag was added as a granulation accelerator.
It is known to mix about 2% and granulate it using polyvinyl alcohol or the like as a binder.
また、塩化カリに尿素その他の窒素成分を２６重量を程
度用いて造粒して硬化させながら粒状肥料とすることも
行なわれている。It is also practiced to granulate potassium chloride with urea or other nitrogen components in an amount of about 26% by weight and harden it to form a granular fertilizer.
（発明の解決しようとする問題点）
しかし、粒状化促進材としてシリコマンガン鉱滓を使用
する方法においては、得られた粒状塩化カリ肥料の平均
硬度が０．１５に８７粒と低く、したがって袋詰め又は
運搬時に破壊されてしまうなどの難点がある。(Problems to be Solved by the Invention) However, in the method of using silicomanganese slag as a granulation accelerator, the average hardness of the obtained granular potassium chloride fertilizer is as low as 0.15 and 87 grains. There are drawbacks such as the possibility of destruction during transportation.
塩化カリに尿素その他の窒素成分を用いて造粒する方法
においては、尿素の吸湿性か強いのて、硬度低下を生じ
てこれも袋詰め又は運搬時に耐えることかてきなかった
。In the method of granulating potassium chloride using urea or other nitrogen components, urea is highly hygroscopic and hardness decreases, making it difficult to withstand bagging or transportation.
（問題点を解決するための手段）
そこで、この発明においては十分な硬度を有する粒状塩
化カリ肥料を提供することを目的として鋭意研究の結果
、この発明では塩化カリに、粒状化促進材として苦土肥
料又は石灰質肥料の一種又は二種以上を２〜１８重量２
混合して造粒した粒状塩化カリ肥料を提案するものであ
る。(Means for Solving the Problems) Therefore, in this invention, as a result of intensive research aimed at providing a granular potassium chloride fertilizer having sufficient hardness, this invention uses potassium chloride as a granulation accelerator. 2 to 18 weight 2 of one or more types of fertilizer or calcareous fertilizer
We propose a granular potassium chloride fertilizer that is mixed and granulated.
ここて、塩化カリとしては例えばカリウム成分を純分に
して５５〜６２重量２程度含むものか使用される。Here, as the potassium chloride, for example, one containing about 55 to 62 parts by weight of pure potassium component is used.
また、苦土肥料としては例えは酸化マグネシウムを主成
分とする軽焼マグネシウム、水酸化マグネシウム、炭酸
マグネシウム、硫酸苦土肥料、水醇化苦土肥料、加工苦
土肥料、腐植酸苦土肥料。In addition, examples of magnesium fertilizers include light burnt magnesium whose main component is magnesium oxide, magnesium hydroxide, magnesium carbonate, sulfated magnesium fertilizer, hydrated magnesium fertilizer, processed magnesium fertilizer, and humic acid magnesium fertilizer.
リグニン苦土肥料、副産苦土肥料、及びこれらの苦土肥
料を二種以上を混合した混合苦土肥料等を使用すること
がてきる。A lignin magnesium soil fertilizer, a by-product magnesium soil fertilizer, a mixed magnesium soil fertilizer made by mixing two or more of these magnesium soil fertilizers, etc. can be used.
更に、石灰質肥料としては消石灰、炭酸カルシウム肥料
、貝化石肥料、副産石灰肥料、石灰質肥料に、他の石灰
質肥料、苦土肥料又はほう素質肥料を混合した混合石灰
肥料等を使用することかできる。Furthermore, as the calcareous fertilizer, slaked lime, calcium carbonate fertilizer, shellfish fossil fertilizer, by-product lime fertilizer, mixed lime fertilizer in which calcareous fertilizer is mixed with other calcareous fertilizer, magnesia fertilizer, or boronous fertilizer, etc. can be used. .
また、苦土肥料又は石灰質肥料の一種又は二種以上の含
有量を２〜１８重量２としたのは、含有量か２重量２以
下では造粒することかてきず、含有量が１８重量％以上
では粒状肥料中のカリウム成分が高濃度のもの（４８重
量２以上）が得られないためである。In addition, the reason why the content of one or more types of magnesia fertilizer or calcareous fertilizer is set to 2 to 18% by weight is that if the content is less than 2% by weight, it will not be possible to granulate it, and the content will be 18% by weight. This is because a granular fertilizer with a high concentration of potassium component (48 weight 2 or more) cannot be obtained with the above method.
なお、造粒に際しては結合剤を使用しなくても造粒する
ことができるが、結合剤として造粒する方がよく、この
場合結合剤としては従来より使用されているポリビニル
アルコール、リクニンスルフオン酸塩等を使用すること
かでき、更に造粒は従来の方法で行なうことかできる。Although granulation can be performed without using a binder, it is better to use a binder as the binder. Foonate salts and the like can be used, and granulation can be carried out by conventional methods.
また、造粒に際してはリン酸成分を配合してリン酸カリ
の複合肥料としてもよく、この場合リン酸成分としては
過リン酸石灰、重過リン酸石灰等を使用することがてき
る。Further, during granulation, a phosphoric acid component may be blended to form a composite fertilizer of potassium phosphate, and in this case, as the phosphoric acid component, lime superphosphate, lime heavy superphosphate, etc. can be used.
（発明の効果）
以上要するに、この発明によれば粒状化促進材として軽

リ肥料を得ることができる。(Effects of the Invention) In summary, according to the present invention, a granular potassium chloride fertilizer having sufficient hardness can be obtained by using a magnesium fertilizer such as lightly burnt magnesium or a calcareous fertilizer such as slaked lime as a granulation accelerator. can.
したかって、この発明により得られた粒状塩化カリ肥料
を他の粒状肥料と混合して袋詰めしても、袋詰め或は運
搬の際に破壊されることもなく、更に施肥する場合には
他の粒状肥料と均一な散布かできる。Therefore, even if the granular potassium chloride fertilizer obtained according to the present invention is mixed with other granular fertilizers and packed in bags, it will not be destroyed during bagging or transportation, and when further fertilizing, other granular fertilizers will not be destroyed. Granular fertilizer and uniform distribution are possible.
