Lime kilns can be classified into three general groups the vertical kiln, rotary kiln and the miscellaneous kiln. In this work, a rotary kiln was designed. Rotary kiln Rotary kilns are an advanced thermal processing tool used for processing solid materials at extremely high temperatures in order to cause chemical reaction or physical change.
Rotary kilns consist of a rotating cylinder inclined at an angle of 3 to 4 degrees to the horizontal. Limestone, chalk or Dolomite is fed into the upper back end, and fuel plus combustion air is fired into the lower front end. The product is then discharged from the kiln into a cooler, where it is used to pre-heat the combustion air.
All maintenance procedures are important and contribute to achieve a reliable operation. Lubrication in the areas discussed, with appropriate solid lubricants is one such step contributing to a well-maintained kiln. References. 1. CHAPMAN, R.P Lime Kiln differential Motion Measured Between Pads and Tires, Pulp amp Paper, October 1991.
A lime kiln uses heat, motion, and airflow to convert lime mud to lime, or in chemical terms, calcium carbonate to calcium oxide. This process is referred to as quotcalciningquot. The most common lime kiln designed found at kraft pulp mills is the rotary lime kiln.
