## Ball Mills An Overview Sciencedirect Topics

for many decades the two-compartment ball mill in closed circuit with a high-efficiency separator has been the mill of choice. In the last decade vertical mills have taken an increasing share of the cement milling market, not least because the specific power consumption of vertical mills is about 30% less than that of ball mills and for finely the basic parameters used in ball mill design rod mill or any tumbling mill sizing are; material to be ground, characteristics, bond work index, bulk density, specific density, desired mill tonnage capacity dtph, operating solids or pulp density, feed size as and maximum chunk size, product size as and maximum and finally the type of circuit openclosed
