The rotary cement kiln is the most vital device in a cement plant, it is the place where the raw meal is burnt and calcined into cement clinker. Cement rotary kiln plays a variety of roles in the cement production line at the same time. It is not only a combustion device, but also a heat exchange device, a chemical reactor, and a conveying device

The black-ash cylinder was a batch process, otherwise similar. It is interesting to note that the Navarros, who first successfully used a continuous rotary kiln for portland cement, had in 1886 operated a batch-process rotary furnace for burning “natural” cement. It was 24’ × 12’, “similar to a large peanut roaster”
