Optimization of a fully air-swept dry grinding cement raw meal ball

There had been a few attempts to relate their model with air flow through the mill, feed rate, feed size distribution, material filling and ball filling (Viswanathan, 1986, Zhang, 1992). Air swept ball mill model proposed by Austin et al. (1975) was validated by Apling and Ergin (1994) using the industrial scale data from a cement grinding circuit.
