Rotary kiln alignment methods have come a long way in the recent past, making alignments faster and more precise than ever before. Routine inspections and realignment in the event of misalignment should be a part of your regular maintenance program in order to keep your kiln.
Rotary kiln burner has many types like three-channel, four-channel and multi-channel, and we can choose from them according to our actual needs. Here we take multi-channel type as an example. The multi-channel type rotary kiln combustor is specially designed to roast materials in rotary kiln.
Is fed into a rotary kiln where it is dried and heated counter-currently by combustion gases from an oil or gas burner at the other end of the kiln. As the mud temperature reaches about 800oC 1470oF in the calcination zone of the kiln, CaCO3 decomposes into CaO and CO2 Reaction 3. The resulting CaO or reburned lime is reused in the causticizing.
HarbisonWalker International offers THERMAX and Rib Back brick. Both have hollowed-out cold faces that help provide insulation, thereby giving our customers cooler shell temperatures. Tumblers are precast or cast in place and are installed in lime rotary kilns to agitate the load. This provides improved heat transfer and lime quality.
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 fuelair.
Metso KFS has been using CFD as an integral part of its kiln burner design process since it was founded in 1999. Metso KFS recognised very early on the importance of the interaction between the combustion and the material bed in rotary kilns. As a result, Metso KFS has developed a proprietary lime bed chemistry module to be fully coupled with CFD.

Rotary Dryer Design Working Principle. First is the kiln this provides the heat the burner is inside this portion the fuel for the burner is usually diesel although heavy crude oil could be used in some cases to be able to generate enough heat to dry the concentrate air must be added by way of a blower in front of the kiln is the point that the wet concentrate enters the drier.
The Metso KFS system is ideal for existing rotary kiln operations based on straight pipe burner technology. A key to a safe kiln warm-up is the ability to provide a stable flame for an effective and controlled heat release profile. The Metso KFS HeatSafe Burner HSB design is based on the proven Metso KFS OptiMix integrated kiln burner.
