The circuit was comprised of ball mill, static classifier and dynamic classifier and in the current flow sheet the fine product of static classifier is sent to feed stream of dynamic classifier. However, it was experimentally proved that sending static fine to the final product silo had several benefits.
COFE the CAPEOPEN Flowsheet Environment is an intuitive graphical user interface to chemical flowsheeting. COFE has sequential solution algorithm using automatic tear streams. COFE displays properties of streams, deals with unitconversion and provides plotting facilities.
When the test ball mill is run in open circuit the design feed rate is tonnes/hour. Figure 4 compares the predicted size distributions from the open circuit ball mill with feed rates of, and tonnes/hour respectively. As might be expected, the larger the feed rate the coarser the grinding mill discharge product.
It was found that the ball mill consumed kWh/t energy to reduce the F 80 feed size of lm to P 80 product size of lm while stirred mill consumed kWh/t of energy to produce ...

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.
