INVESTIGATION OF GRANULATION PROCESS OF POWDERY MATERIALS AND INFLUENCE OF INTENSIFYING ADDITIONS ON STRENGTH OF SUPERPHOSPHATE GRANULES
The possibilities of improvement of the qualitative indices of superphosphate fertilizers with use of intensifying additions (manganese MnO and aluminum Al2O3 oxides with ammonium hydroxide (NH4OH) favoring decrease of porosity and increase of granules strength are considered. The mass-exchange problem of moistening granules has been solved, the dependence of thickness of moistening and strength on granule porosity has been determined
Keywords : superphosphate fertilizers, moistening, mass-exchange, diffusion, porosity, strength, mineral additions
