Shaft Kilns - Lime Vertical Shaft Kiln Exporter from Vertical kilns work on a batch-type system rather than continuous feed, and the upper kiln area is used for preheating. Typically, the kiln would be shut down, the batch would be charged and the burners would be re-fired.
Although shaft kilns in different versions and sizes are used in a wide range of industries (lime, sugar, soda, iron & steel, etc.), what they have in common is that their refractory linings always consist of several layers. Usually, these consist of several insulating layers, the permanent lining, and the wear lining. Similarly, the zones in a ...
Vertical Shaft Kilns. 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 ...
