Rotary cement kiln is regarded as the heart of cement manufacture in any cement plant widely used to convert raw material into clinker. The capacity of a plant is determined by the production in the kiln whose sizes can be very large to handle higher production capacities of as much as 10000 tonnes per day (tpd) of raw meal to be processed. The ultimate cement quality is determined at the kiln.
