what is the main use of a single shaft kiln

the cold end of the kiln is the main gas moving fan. It pulls the combustion products, carbon dioxide from calcining, and the water vapor from the wet mud out of the cold end of the kiln. The ID fan is used to control the total air flow into the kiln for combustion, so controls the excess air or excess oxygen in the flue gas from the kiln.

Latest drive systems for rotary kilns. The rotary kiln is the core of lime and cement clinker production. In the slightly inclined cylindrical tube, which rotates around its longitudinal axis during the firing process, the lime powder is heated up to 1450 °C and burned into cement clinker. The rotation has both a transport and an air injection ...

01-03-2013· There are different designs of limekilns, the vertical shaft kiln being one of the most used designs, because of its thermal efficiency. A vertical shaft kiln ( Fig. 1 ) is basically a moving bed reactor with the upward flow of hot combustion gases counter-current to the downward flow of limestone particles that undergo calcination at elevated temperatures usually above 900 °C.

Each shaft cycles through the burning and non-burning mode about every 10 minutes. There is a large reduction in the fuel used by the two-shaft kiln compared to the single shaft kiln. Shaft kilns have capacities for producing up to 800 tonnes of lime per day. Quicklime is generally sold either as granules or as a finely ground powder.
