<Industrial Application Field> The present invention uses Mg(OH) 2 , MgO as a curing accelerator.
This invention relates to granular potassium chloride fertilizer granulated using. <Conventional technology> When using potassium chloride crystals as the potassium ingredient 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 applying fertilizer after unpacking the bag, it is difficult to uniformly spread each component of the compound fertilizer. Therefore, attempts have been made to blend potassium chloride in the form of granules, but potassium chloride is difficult to granulate and cannot be granulated alone. On the other hand, in order to improve the granulation properties of potassium chloride, about 15% by weight of crushed silicomanganese slag was mixed as a granulation accelerator, and polyvinyl alcohol was used as a binder to granulate the mixture. Are known. Additionally, potassium chloride is granulated with about 26% by weight of urea and other nitrogen components and hardened to form a granular fertilizer. <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 Kg/granule;
Even if only a binder such as povinyl alcohol is used, a granulated product with high hardness cannot be obtained, and therefore there is a problem that the granulated product is destroyed during bagging or transportation. In the method of granulating potassium chloride with urea or other nitrogen components, since urea is highly hygroscopic,
This also caused a decrease in hardness and could not withstand packaging or transportation. <Means for solving the problems> The present invention was proposed in view of the above, and includes potassium chloride with Mg(OH) 2 and/or as a hardening accelerator.
The present invention relates to a granular potassium chloride fertilizer characterized in that it is granulated by mixing 2 to 18% by weight of MgO and lignin sulfonate and/or polyvinyl alcohol as a binder. Here, as the potassium chloride, for example, one containing about 55 to 62% by weight of pure potassium component is used. In addition, Mg(OH) 2 and MgO used as hardening accelerators in the present invention include, for example, lightly burnt magnesium containing magnesium oxide as a main component, magnesium hydroxide, magnesium carbonate, sulfate magnesium fertilizer, hydroxide magnesium fertilizer, Processed magnesium soil fertilizers, corrosive acid magnesium soil fertilizers, lignin magnesium soil fertilizers, by-product magnesium soil fertilizers, and mixed magnesium soil fertilizers in which two or more of these magnesium soil fertilizers are mixed can be used. In addition, the amount of Mg(OH) 2 and/or MgO added was
~18% by weight is because if the content is less than 2% by weight, the hardening of the granular fertilizer will not be sufficient, and if the content is less than 18% by weight, the potassium content in the granular fertilizer will be high (48% by weight or more). ) is not obtained. Although granulation can be performed without using a binder, it is better to use a binder as the binder. Acid salts and the like can be used, and further granulation can be carried out by conventional methods. Regarding granulation, a phosphoric acid component may be added to form a composite fertilizer of potassium phosphate. In this case, as the phosphoric acid component, lime superphosphate, lime heavy superphosphate, etc. can be used. <Effects of the Invention> As explained above, according to the present invention, Mg(OH) 2 and/or MgO is mixed as a curing accelerator,
By mixing lignin sulfonate and/or polyvinyl alcohol as a binder and granulating the mixture, a granular potassium chloride fertilizer having sufficient hardness can be obtained. Therefore, even if the granular potassium chloride fertilizer obtained by the present invention is mixed with other granular fertilizers and packed in bags,
It will not be destroyed during bagging or transportation,
Furthermore, when applying fertilizer, it can be uniformly spread with other granular fertilizers. <Examples> Examples of the present invention will be shown below. Example 1 Potassium chloride 87.1% by weight Lightly calcined magnesium 9.0% by weight Lime heavy superphosphate 3.7% by weight Polyvinyl alcohol (binder) 0.2% by weight Based on the above composition, among the components, potassium chloride, lightly calcined magnesium, and heavy superphosphate Acid lime was added and mixed, and then granulated with polyvinyl alcohol solution. Regarding the granulated potassium chloride fertilizer, the water-soluble potassium component content (wt%) and hardness (Kg/
The results of measuring the grain size are shown in Table 1 below.

とが明らかとなつた。[Table] * In the table, the hardness is the average value of 20 grains measured using a Kiya hardness meter.
As is clear from the above results, values of 48% by weight or more were obtained for the water-soluble potassium component in all cases, and values of 1.5 kg/grain or more were obtained for the hardness. From this, the granulation of potassium chloride is promoted by using lightly calcined magnesium as a granulation promoter,
Moreover, it has become clear that a granular potassium chloride fertilizer with high hardness can be obtained.
