    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

    Ever since the first Ransome kiln (until recently) rotary kilns were turned by means of a single girth gear (known as the turning gear) surrounding the kiln. The early kilns turned very slowly, the girth gear meshing with a worm gear. Subsequently full-speed rotation of kilns in the range 0.5-1.5 rpm became standard, and the gear meshed with a pinion running at 10-20 rpm. The pinion shaft was ...

  • What's the Difference Between Rotary Dryers and Kilns?

    Rotary dryers and rotary kilns share similar thermal processing functions, but each is intended for very different industrial applications. Rotary dryers operate at inlet temperatures between 600 and 1400ºF, and are predominately used to draw moisture out of a material. Rotary kilns, on the other hand, are utilized to cause a phase change or a chemical reaction within a material.
