IBU-tec The Rotary Kiln Experts for Trials and Production

Rotary kilns (sometimes called calciners or rotary furnaces) are used for thermal treatment processes such as calcination, sintering, pyrolysis and firing, as well as for oxidation and reduction.These treatments can be applied to powders, granulates, suspensions and green bodies.A rotary kiln consists of a cylindrical, rotating body mounted between stationary material feed and outlet housings.

Rotary Kiln Design: Sizing

Data AcquisitionDetermining Kiln SizeConclusionThe first step in sizing a rotary kiln entails thermal and chemical analyses that gather information on reaction temperatures, heat transfer properties, potential unintended reactions, and more. Depending on the process and the material, some of this data may be published.Upon completion of a thorough thermal and chemical analysis, additional data is gathered around the source material and the many process variables that can in在feeco上查看更多信息

Rotary kiln - Wikipedia

OverviewHistoryPrinciple of operationConstructionOther equipmentSee alsoSources and further reading

The rotary kiln was invented in 1873 by Frederick Ransome. This is made from rolled mild steel plate, usually between 15 and 30 mm thick, welded to form a cylinder which may be up to 230 m in length and up to 6 m in diameter. Upper limits on diameter are set by the tendency of the shell to deform under its own weight to an oval cross section, with consequent flexure during rotation. Length is not necessarily limited, but it becomes

Cement Kilns: Design features of rotary kilns

The rotation of the kiln lifts the feed up the side of the kiln, and the energy required to maintain its centre of gravity above the lowest (6 o'clock) point is the main component (80-90%) of the energy consumed. In the case of kilns containing curtain chains, these also produce an eccentric load. Rotary kilns have always had variable speed drives.
