    The technology of rotating drums has been available for over 100 years, yet it remains in active use in many of its traditional applications. The rotary drum provides efficient means for both heat and mass transfer in the processing of slurries and other condensed mixtures. The most well-known uses are lime, pigment and cement manufacture, as well as the lime sludge reburning in the recovery cycle of the wood pulping process. Other uses are in manufacture of oxides (zinc, lead), reduction of ores and waste incineration. With fostered pursuit for energy-efficiency everywhere in the industry, a new simulation tool, which combines computational fluid dynamics (CFD) with multiphase chemistry allows for improved insight on the kiln operation.
