OPERATIONS STRATEGIES FOR VERTICAL SHAFT LIME KILNS

The Kiln Feed is transported to the Noduliser with the help of an air-lift. At this stage, water is sprayed on the feed (appx. 10%) to make nodules, which are then fed into the Vertical Shaft Kilns (VSK) through feed chute for burning and fusion. The temperature goes up to 1400 C in the burning zone. The nodules travel very slowly in the kilns.
