| Abstract: | The distribution of moisture content for flash dryers with Circulating system ofsolids was investigated, The density function for distribution of moisture content was developed' The moisture content contribution of drying FeSO4 7H2O was calculated. The resultsshow a significant effect Of the circulation -- ratio on the distribution of moisture content.When the circulation --- ratio is increased, the fraction of the dryer particales in the productrises the average moisture content decreases, and the distribution of moisture content becomes more dispersive. |
