Example 2
A production method of an instant fertilizer comprises the following steps:
the fertilizer can not only improve the soil fertility, but also is an important measure for improving the yield of crops in unit area, the fertilizer is the most basic and the most important material input for agricultural production, according to the statistics of the Food and Agricultural Organization (FAO) of the United nations, the fertilizer accounts for about 40-60% of the total share of the fertilizer for increasing the yield of crops, and the fertilizer is dissolved in water quickly and slowly, so that the method is the most intuitive method for farmers to identify the quality of compound fertilizers.
1. The solubility of a chemical fertilizer has a close relationship with temperature, and the solubility of a general chemical fertilizer increases with the increase of the temperature as follows:
in the production process, each formula has an optimal liquid phase amount during granulation, and the lower the temperature of materials during granulation, the more water is needed for granulation; the higher the temperature of the material is, the greater the solubility of the material is, and the less the water is needed for granulation, so the temperature of the material during granulation is increased, and the water content of the material during granulation can be reduced, which is an important means for improving drying capacity and increasing yield, and the temperature standard of the material during granulation is low concentration and ambient temperature; high concentration, 60-65 ℃.
2. Granulation of high-concentration fertilizer and low-concentration fertilizer
2.1, most of raw materials used by the low-concentration fertilizer are superphosphate, the solubility of the superphosphate is low, the change of the material temperature has little influence on the solubility of the superphosphate, the materials are granulated at normal temperature, the temperature of the materials in a dryer is increased, the total liquid phase amount of the materials in the dryer cannot exceed the standard, and therefore, the problems of large balls and the like cannot occur during drying.
2.2, because the solubility of the used raw materials of high concentration fertilizer is great, after improving the material temperature to 60~65 ℃ during the granulation, required moisture can significantly reduce, the required liquid phase of granulation mainly depends on improving the solubility of material and satisfies, because the material temperature has reached 60~65 ℃ during the granulation, the range of material temperature improvement is less again in drying process, so the material can normally go on when drying, if the material makes into the qualified granule of 02~ 4mm below 60 ℃, the required moisture of granulation must increase, after the material gets into the desiccator, along with the improvement of temperature, the solubility constantly improves, the liquid phase can seriously exceed standard, can appear bold and mashed mud in drying process, make the drying unable normally go on.
