In the production of potassium chloride granular fertilizer, fertilizer granulator can be used to granulate powder. The particles produced by disc granulator are spherical and have good strength, which can be widely used in agricultural production.
In the granulation process of disc pan granulator, it is necessary to add a binder to make the granules shape. Binder can be compounded by common inorganic minerals in a certain proportion. Binder has synergistic effect when potassium chloride is pelleted. The effect of pelletizing rate and particle strength is good when the binder is used for pelletizing. Potassium chloride was granulated by disc pan granulator machine, and the granules were spherical.
NPK fertilizer production line deals with potassium chloride fertilizer. First, all raw materials are mixed by the batching system, and the material is crushed by chain mill to the appropriate size. The disc granulator makes the powder into granules. After drying and cooling, the granules of potassium chloride are coated with protective film by the fertilizer coating machine to complete the granular processing of potassium chloride.
When applying potassium chloride, attention should be paid to the appropriate period of potassium application. Generally, the application period of potassium fertilizer should be early or not late, and should be used as base fertilizer and early recovery period. When the application amount of potassium fertilizer is less, it can be used as base fertilizer once, and when the application amount of potassium fertilizer is more or the soil texture is lighter, the application effect is better divided into base fertilizer and topdressing fertilizer. Soil nutrients and fertilization status should also be taken into account in determining the suitable application period of potassium fertilizer. In severe potassium deficiency soils, all potassium fertilizers should be used as base fertilizers in medium soil potassium supply, and suitable organic fertilizers should be applied as base fertilizers, combined with topdressing.
Note the method of application of potassium chloride. The concentrated application of potassium fertilizer is beneficial to improve its utilization rate and obtain better results. However, it is not advisable to have direct contact with seeds or seedlings. For general crops, a combination of soil fertilization and foliar fertilization can be used.
