Abstract
In the circulating fluid bed (CFB) (0. 104 m ID × 2. 35 m height) dryer, the influence of material properties on the drying and separating rate of the CFB was researched, with starch, calcium carbonate, and alumina as objects of study. The effects of particle diameter and the humidity of drying medium were studied on the drying and separating features of the CFB, with aluminum oxide as a studying object. It reveals that the CFB dryer is applicable to drying and separating of C-class particles with various characteristics. The drying rate of calcium carbonate is quicker and easy to be separated compared with aluminum oxide and corn starch; the gas velocity has a great influence on the drying rate of corn starch and alumina oxide; drying rate and separating rate increase with the increasing of particle size and reduce with the increasing of drying medium humidity in the operating range of experiment.
