Why do relatively coarse calcareous phosphate particles perform better in a static-bed calciner?

The calcination process is a direct and clean process for upgrading of phosphate ores with high-carbonate contents. In this study, calcination experiments of calcareous phosphate were conducted. Different size fractions were used to evaluate their performance while heating in a static-bed furnace at...
