The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill
the mill power and the efﬁciency of the mill operation (Van Nierop and Moys, 2001) If a SAG mill has been designed with a conventional power or speciﬁc energy model which do not con-sider the projected feed size distribution it is likely that this mill will reach the expected power ,
2 MODELLING THE SPECIFIC GRINDING ENERGY AND BALL-MILL SCALEUP Ball-mill scale up (Bond’s Law)Data: zBond work index w i zFeed D f and product d size (both 80% cumulative passing) Result: The specific grinding energy w Mill power draw P = wT, where T the mill capacity Mill dimensions (from Tables or charts)
a conventional ball mill circuit The result: an increase in production of approximately 25 percent, and a reduction in specific power consumption of about 10 percent compared to a conventional ball mill system Semi-finish grinding Upgrading a ball mill system with an HRP in a semi-finish mode is a simple solution, and installation is easy
