Rotary Kilns. Rotary kilns are the most complex type of lime kiln and are used for large-scale production. They consist of a long, rotating cylinder that is inclined at a slight angle to the horizontal. Limestone is fed into one end of the cylinder, and as it moves through the cylinder, it is heated to high temperatures.
