Rotary kiln Wikipedia

The rotary kiln was invented in 1873 by Frederick Ransome. Kiln shell This is The speed of material flow through the kiln is proportional to rotation speed, and so a variable speed drive is needed to control this. When driving through rollers, hydraulic drives may be used. These have the advantage of developing extremely high torque.

[PDF] Modelling of Rotary Kilns Semantic Scholar

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

They rotate at about 1 rpm. Dewatered concentrate is fed continuously to the upper end of the rotating kiln. Coal (about 5% of the feed) is also added continuously along with pelletized recycle calcination/reduction kiln dust. These materials flow slowly down the rotating kiln and out the hot discharge (lower) end of the kiln.
