Burning fuel, and the final 10 are from transportation and electricity.5 Clinker is made by heating limestone, clay, bauxite and iron at temperatures of than 1,400˚C in a long rotary kiln. It is then interground with gypsum and other cementitious materials to produce cement. Producing the high temperatures necessary to drive the reaction.

Better Cement Coating Firebricks For Rotary Kiln Burning

Kiln Burning Zone Temperature Measurement - The Kiln is the heart of the plant – what an entire cement plant is dimensioned around, and where most of the final chemical reactions take place. The kilns play a key role in ensuring optimal quality clinker. The rotary kiln consists of a tube made from a mild steel plate and slowly rotates on its axis.

Better Cement Coating Firebricks For Rotary Kiln Burning

A burner for a rotary kiln consists of a central pipe (5) for introducing an oil or gas lance, a first concentric pipe (8) for introducing primary air and a second concentric pipe (1) for introducing a mixture of solid fuel and carrier air into the burning zone of the kiln. The pipes (5, 8 and 1) form mutually annular channels, the primary air channel being located inside the solid fuel air.
