INVESTIGATION OF GRANULATION PROCESS OF POWDERY MATERIALS AND INFLUENCE OF INTENSIFYING ADDITIONS ON STRENGTH OF SUPERPHOSPHATE GRANULES

G.I.Kelbaliev, V.M.Samedli, M.M.Samedov, R.K.Kasimova

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
