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 ......

Preheaters
Preheaters. Lime kiln preheaters are used to "preheat" the limestone prior to the limestone being fed into the kiln. Hot kiln exit gases that might otherwise be exhausted to the environment are used to heat the limestone. This improves operating efficiency and reduces operating costs. Lime preheater floors are very abrasive service ......
