Process for producing a nitrogen-potash fertilizer |
| abstract |
The invention relates to the chemical industry and can be used while producing granulated nitrogen-potash fertilizers. An ammonia nitrate melt in the amount of 33-69 weight %, potassium chloride in the amount of 22-65 weight %, and a specific mineral admixture—phosphogypsum in the amount of 2-9 weight % are fed into a mixture as well as ammonia, which is necessary for keeping pH value of the mixture within the range of 6.5-7.5. The obtained slurry is sprayed onto a recycle product in a drum granulator and granulated under a recycle ratio being equal to 1:(2-2.5), the final product is dried. A stirring is carried out under the optimal operational mode within the temperature range of 100-130° C. during 20-30 minutes. Due to such conditions, a productivity rate of the process is increased and granules of the fertilizer have higher strength and reduced leachability from the soil. |
