A rotary kiln is a pyroprocessing device used to raise materials to a high temperature (calcination) in a continuous process. Materials produced using rotary kilns include: Cement Lime Refractories Metakaolin Titanium dioxide Alumina Vermiculite Iron ore pellets Incineration of biomedical waste process like pyrolysis {with without passing hot gases} They are also used for roasting a wide variety of sulfide ores prior to metal extraction.
