Twin Shaft Lime Kiln Working Process. Feed Preparation: Limestone, typically in the form of crushed or ground stone, is prepared for feeding into the kiln. The limestone feed may be preheated to reduce the energy consumption of the kiln. Feeding: The prepared limestone is fed into the twin shaft lime kiln through the feed chute or hopper. The limestone enters the kiln at …

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.

How a lime vertical kiln works. In a lime vertical kiln, limestone is fed into the top of the kiln and heated to a high temperature, typically between 900 and 1200°C. The limestone undergoes a series of chemical reactions, including decomposition and carbonation, to produce quicklime. The quicklime is then cooled and discharged from the bottom ...
