A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage [1]) 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.

1.. IntroductionConventionally multicompartment ball mills are used in finish grinding of cement. However, they are relatively inefficient at size reduction and have high energy consumption, so it is increasingly common to find grinding technologies such as High Pressure Grinding Rolls (HPGR), vertical mills and Horomill ® in cement plants. As recorded in the literature, Horomills ...

Assessment of mills to established fatigue design rules. A model of the mill investigated in this study was developed using the original design geometry during the auditing phase of the project. The charge load used for design was 45% total charge with 40% ball charge, as is commonly used in mill specifications for the maximum structural load.

The grinding process in ball mills and vertical roller mills is fundamentally different [15]. Following are advantages of VRM over Ball Mills with reference to these issues: • Strong drying ability Inlet hot air from Kiln can dry materials with 20% water content. (max moisture 20% vs. 3% in ball mill) [15], [16]. •

Wilczek: The mill accepts a maximum particle size of about mm for hard and up to 4mm for softer materials. One typical characteristic of the mill is the high energy density, 1020 times higher compared to a ball mill, resulting in a very compact design. The high energy density in the small grinding chamber requires a fast material transport.
