Improvement of Lime-Burning Rotary Kilns

The main advantage of rotary kilns due to which they found widespread – is the possibility to produce high-quality soft burnt lime from small raw materials with various properties. At this, the high quality lime can be obtained practically at any rotary kiln. The main disadvantage of rotary kilns is low economic efficiency, due primarily to high fuel consumption and high expenditures for construction and maintenance. Main elements and systems of the rotary kiln, which determine its performance with different raw materials, the design of the lime cooler; designs of seals of hot and cold ends; the design of the burner device; the design of the kiln lining; the design of the kiln feeding unit; designs of internal or separate pre-heaters of raw materials. A brief description of modern, practically applicable main elements and systems of rotary kilns is presented; proposals and recommendations on their introduction and improvement are also given.
