Measures to improve roundness of potassium sulfate compound fertilizer
The basic principle of granular compound fertilizer and the reasons for the irregularity of compound fertilizer particles are briefly described,measures to improve the roundness of potassium sulfate compound fertilizer particles from the aspects of equipment,ingredient process,ingredient composition and production technology are proposed,and the optimal inlet temperature of 150℃and outlet temperature of 75℃are determined for the drying machine of the production conditions and formula in this study.Analytical models for the inlet and outlet temperature control of a dryer are established to provide convenience for related research.
