2001-1-26  A novel approach to modeling mass transfer in rotary kilns is explored. The movement of gas in the interparticle voids in the bed of the kiln is considered, where particles move concentrically with the geometry of the kiln and gas is entrained by these particles. A reactor modeling approach has been used to derive effectiveness factors for the bed as a function of bed fill, reaction kinetics ...
