| Abstract: | It is analyzed the drying principle of tray dryer： idealizing wet vanadium- bearing material as wet multi- hole material,and with that as basis,the material is analyzed for its heat and mass transfer and idealized as one dimensional diffusion model. The drying curve is gotten with computer simulation based on the structure of tray dryer and materials moving track. With this program,the influence of main shaft speed,charging rate,temperature of heating tray and initial moisture on material heat and mass transfer process is analyzed. |
