A lime kiln uses heat, motion, and airflow to convert lime mud to lime, or in chemical terms, calcium carbonate to calcium oxide. This process is referred to as "calcining". The most common lime kiln designed found at kraft pulp mills is the rotary lime kiln.
As the popularity of lime kilns grew and the amount of limestone on the surface diminished, farmers dug into the ground to expose more limestone and thus started the practice of quarrying. As illustrated by Miller's photographs and diagrams, lime kilns came in all shapes and sizes. Most were single-batch kilns built into a hill along a roadside.
