The heart of a lime plant is the kiln. The prevalent type of kiln is the rotary kiln which accounts to about 90 percent of all lime production in the world ( Ellis 1960 ). The kiln is a long, cylindrical, slightly inclined, refractory- lined furnace, through which the limestone and hot combustion gases pass counter currently.

Lime Production from Limestone Grade 12U Chemistry
May 07, 2013· An application of a chemical equilibrium for an industrial system is lime production from limestone. The products which are made from burnt limestone are called lime (ie. quicklime and hydrated lime). Limestone is naturally occurring, and it also consits of minerals in small pieces. Presently, limestone products are used as a crucial part in most industrial processes.
