The study indicates that for a dry type cement production process, the carbon dioxide emission intensity for kiln feed preparation process is about 5.4 kg CO 2 per ton cement produced. In this study, the raw mill of a cement plant is considered and its performance based on the first and second laws of thermodynamics is investigated.

Our results suggest that integrating an air classifier into an open-circuit ball mill can increase the production rate by 15% or increase the cement-specific surface area by 13%. A single-compartment mill entails a pre-milled feed for proper operation, whereas a two-compartment mill yields a finer cement product than a three-compartment mill.

Pre-grinding to a fineness of 2500- 3000 Blaine is per formed in the coarse grinding mill. In the open circuit fine grinding mill, fine particles of up to 6000 Blaine can be attained [143b]. The one-compartment fine grinding mill is filled with 4- 8 mm cylpebs grinding media; because of its small size, the grinding media are called minipebs.
