Rotary kilnsthatproduce limetypically have fourrefractoryzones.Longprocess kilnsrequire abrasion resistant, high strength alumina brick for the charging zone, where abrasion of the stone can be particularly severe.Short preheaterkilnsnormally do not have a charging zone that sees high abrasion as preheated stone is partially softened.

The axis ofrotationis tilted so that gravity continuously moves a product like limestone from the high end, down the furnace toward a burner at the low end where the product is discharged into the clinker cooler.Rotary kilnsare used in a variety ofprocesses, though primarily in the production oflime, dolomite and cement.

Lime rotary kiln’sprocessof preparation is flexible. The high-temperature smoke in vertical preheater can be fully used to turnlimeinto an initial decomposition state. The vertical cooler can be put inkilnheat to instantaneously cool downlime, so product activity is raised and transportation is more convenient.
