Types of lime kilns - techniques and design. Calcining kilns are basically comes in two categories. They are i) rotary kilns and ii) vertical kilns. Both the types of kilns can be designed with any of the solid, liquid or gaseous fuels. Rotary kilns can be long kilns with straight rotary coolers while verticals kilns can be several types.

Lime shaft kilns are stationary vertical kilns where the raw limestone enters at the top and gravity flows through three thermally zoned sections known as the preheating, calcining, and cooling zones. The process heats the limestone from ambient temperature to 900°C, which is the point where the carbon dioxide is driven ...

These three kilns, built by Garwin Mace, date from 1890. Each rectangular kiln, made of rough limestone blocks, has two round vertical shafts lined with firebrick below and iron rings toward the top. Round-arched drawholes (reconstructed in for stabilization) pierce the bottom of each structure on all sides.

They operated independently, producing small amounts of lime for the owner and immediate neighbors. As demand and transportation opportunities grew (canals and railroads), commercial kilns, known as vertical-draw kilns, which produced a large quantity of lime, were built. Many independent and commercial kiln examples survive, relatively intact.

Where the operation is exclusively for the production of lime in vertical or shaft kilns, the quarrying is very simple. The object is to avoid production of fines, and drilling and blasting are designed accordingly. The use of compressed-air drills, both the hand-hammer type and mounted wagon drills, is regular practice.
