A HIGH-CAPACITY STEEL SHELL LIME SHAFT KILN FOR BUILDING-INDUSTRY

The Indian building lime industry falls under the category of small and medium scale sector employing kilns of capacities generally upto 10 tpd. On account of the requirements of changed environment and some inherent drawbacks of the existing masonry kilns, a steel shell lime shaft kiln of 20 tpd capacity has been designed. The process engineering aspects and mechanical design features of the same have been detailed with due cognizance to pollution control measures. It is proposed that the existing low capacity country kilns may be replaced with this moderately high capacity kiln in congested and highly air polluting lime manufacturing centres in the country.
