The costs of fluidized bed calcining of the acidic and re-acidified forms of Purex and Thorex wastes were determined. The wastes were assumed produced by a chemical-processing plant recovering unburned fuel from 1500 tons/ yr of U converter fuel at a burnup of 10,000 Mwd/ton and 270 tons/yr of Th converter fuel at 20,000 Mwd/ton.
Residence time distributions were determined for the continuous processing of cut tobacco in the rotary drum by introducing expanded cut tobacco tracers to the inlet of the processing system using the negative step change method. Effects of rotating speed of the rotary cylinder and solids flow rate on the mixing homogenization and residence time distribution (RTD) of experiment materials was ...
The main characteristics of this pilot scale rotary kiln, which was used to investigate the wall-to-solid heat transfer coe cient in the present study, are summarized in Table 1. Its main part consists of a rotating tube supported on 4 rollers. The tube is surrounded by heating elements (resistors) arranged in …

Rotary Calciner. Rotary calciners (sometimes referred to as rotary kilns) are used for a variety of material processing applications. These high temperature machines process materials into a desired form by changing the state or composition of a material, or removing moisture.
calciners on the calcination process with a particular interest in understanding the scale-up in rotary calciners. Summary of Studies We use the discrete element method (DEM) to simulate the heat transfer and flow of particles in rotary calciners. The DEM is an idealistic tool as it can directly represent heterogeneity in the
