Today, this mill is employed all around the world for the grinding of cement raw material, cement clinker and granulated blast furnace slag. For new plants, the …

Energy consumption and output. Cement mills are normally driven by electric motors. Modern installations draw power of 210 MW. The power (in kW) required to turn a ball mill is approximated by: P = d () m n where d is the internal diameter in metres, j is the fraction of the mill volume occupied by media, m is the total mass of media in the mill, in tonnes, and n is the mill ...

A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.

Correct timing on the maintenance of a first chamber cement mill lining and the successful implementation of an expert system on a cement mill both offer benefits in terms of power consumption (see case studies panel). Accurate process measurements are also key to energy saving opportunities. Air compressors are another area for attention.

3. Factors affecting ball mills Cement fineness vs. grindability Every 100 cm²/g increase in cement fineness increases the mill power consumption by 12 kWh/t for a closed circuit mill 23 kWh/t for an open circuit mill, a sheer waste if this is not required by the market! 20 25 30 35 40 45 50 55 60 2500 3000 3500 4000 4500 5000

Energy Saving Analysis of Cement Vertical roller mill and Discussion on Its Product Performance. Cement grinding process power consumption accounts for about onethird of the total power consumption of cement production process, therefore, reduce the cement grinding process power consumption has been an important issue for industry technical personnel research.

Horizontal roller mills use 6570% of the energy used in ball mills. Roller press (highpressure grinding rolls): In this technology materials are crushed between two counterrotating rollers. These rollers are up to 2 m in diameter and m long. Roller presses use 5065% of the energy used in ball mills.
