Summary: The main trends concerning grinding processes in the cement industry are still higher efficiency, reduction of the power consumption and system simplicity. In the case of new orders, vertical mills have increased their share to over 60 % and ball mills have fallen to less than 30 %.
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.
A comparison between the grinding systems and conventional ball mills applied in cement grinding circuits is given in Table 5. Grinding efficiencies of different systems in grinding of cement to a fineness according to a Blaine of 3,000 cm 2 /g were compared in Table 6.
grinding efficiency of the vertical roller mill combined with an ability to dry, grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system. However, despite these benefits applications of the vertical roller mill for cement grinding are less prevalent.
Cement grinding Vertical roller mills versus ball mills RuCEMRU comparision between vertical roller mill vs ball mill,These differences between cement grinding and grinding of raw materials made it a serious challenge to obtain a good performance of a vertical roller mill in cement grinding Today, however, the OK mill has become .
Cement Ball Mill. The ball mill for clinker is an efficient tool for fine powder grinding. It is mainly used to grind the clinker and raw materials in cement industry and also can be applied in metallurgy, chemical, electric power and other industries to grind all kinds of ores. Cement ball mill is not only suitable for overflow grinding.
The cement grinding system is gradually developed from the earlier simple ball mill system to the ball mill roll press system and roll grinding system. According to the technological process, the cement grinding system is divided into two systems: open flow and coil flow.
The use of highpressure grinding rolls (HPGR) prior to ball mills has become a common practice in cement clinker grinding due to significant energy savings in comparison to ball milling alone.
cement industry the ball mill was really an epochmaking breakthrough as for almost 80 years it was the predominant mill for grinding of raw materials and coal, and still today is the most used mill for cement grinding. Over the last three decades the vertical roller mill has become the preferred mill for grinding of .

Cement grinding. The clinker from the pyroprocessing area is ground in ball mills or roll press + Ball mill combination or vertical roller mills to form cement. Commonly used separators are in closed circuit grinding are: O –sepa, Sepol and Sepax separators to achieve a finish cement fineness of 3000 – 4000 Blaine surface (cm2/gm).
In this study, in order to evaluate and compare the performances of these cement grinding technologies, industrial scale data were collected from HPGRball mill, VRM, Horomill and multichamber ball mill closed circuits. The grind abilities of the raw materials of all circuits were varying in a narrow range of 14–20 kWh/t.
