| titleOfInvention | Additive for widening firing range of potassium-containing mineral fertilizer and potassium-containing mineral fertilizer |
| abstract | The invention discloses an additive for widening the firing range of a potassium-containing mineral fertilizer and the potassium-containing mineral fertilizer, wherein the additive comprises the following materials in percentage by mass: 60-90% of a sodium material, 5-20% of an iron material and 5-20% of a siliceous material; the additive amount of the potassium-containing mineral fertilizer is 1-4% of the total mass of the solid raw materials of the potassium-containing mineral fertilizer. The additive provided by the invention can remarkably broaden the firing range of the potassium-containing mineral fertilizer, reduce the calcining temperature, improve the operation rate of a kiln system, realize continuous and stable production of the potassium-containing mineral fertilizer, save energy, reduce consumption, increase the content of available nutrients in the product, and has good economic benefits and wide popularization and application prospects. |
