A cement mill is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills. Contents. [hide]. 1 History; 2.
o 27-32 kWh/t at 3,000 cm²/g o 39-47 kWh/t at 4,000 cm²/g o 58-69 kWh/t at 5,000 cm²/g. 3. Factors affecting ball mills. Cement fineness vs. grindability. Every 100 cm²/g increase in cement fineness increases the mill power consumption by 1-2 kWh/t for a closed circuit mill & 2-3 kWh/t for an open circuit mill, a sheer waste if.
