Because the reactor is inclined from both the feed end to the discharge end, its rotation causes the iron ore and coal to mix and travel downward towards the exit. The rotational speed of the reactor can be adjusted to maintain the desired loading of the kiln and provide the required time to complete the reduction of the iron ore

The rotary kiln is the core of lime and cement clinker production. In the slightly inclined cylindrical tube, which rotates around its longitudinal axis during the firing process, the lime powder is heated up to 1450 °C and burned into cement clinker. The rotation has both a transport and an air injection effect
