Kiln Types
Some shaft kilns can be operated on natural gas, liquid and solid fuels. This type of kiln tends to produce medium reactivity quicklime, which can then be used in a number of industrial processes including the manufacture of iron and steel and aerated concrete blocks. Quicklime from shaft kilns is also processed into hydrated lime.

Introduction to Iron ore Pellets and Pelletizing processes
At 800 deg C, the FeO of the magnetite iron ore gets converted into Fe2O3 in an exothermic reaction. The liberated heat hardens the green balls which is helpful to withstand the tumbling impact due to the rotation of the rotary kiln. A circular cooler is used for cooling of the fired pellets. Flowsheet of grate kiln process is given at Fig 3.
CFD Modelling of Calcination in a Rotary Lime Kiln
A 2D axisymmetric computational fluid dynamics (CFD) model, coupled to a 1D bed model, has been developed to capture the key processes that occur within rotary lime kilns.
