THE STUDIES OF STABILITY FOR A VIBRATED FLUIDIZED BED WITH DENSE MEDIA

摘要

A vibrated fluidized bed with 148 mm diameter was set up. It was found that bed density is influenced by a number of physical factors associated with the powder (known as heavy medium) and operating parameters. These factors, such as pressure drop of distributor, the ratio of expand of bed, the size and distribution of dense media, were investigated experimentally. Optimum operation parameters were researched.
