For cement grinding, the technology development away from ball mills has taken a different route The development of roller presses in the 1980s took advantage of the benefits of higher-pressure grinding and many presses were retrofitted to ball mills as pregrinders The main benefit was seen at lower Blaines as the first generation of presses suffered from stability problems when attempts
The cement industry in India is probably the most efficient in the world and has a well deserved reputation for technology upgradation The proper selection of plant and machinery, and process systems and auxiliary equipment is not only important from the energy efficiency point of view, but also critical from the plant´s reliability point of
The emergence of Portland cement in the 1840s made grinding considerably more difficult, because the clinker produced by the kiln is often as hard as the millstone material Because of this, cement continued to be ground very coarsely (typically 20% over 100 μm particle diameter) until better grinding technology became available Besides producing un-reactive cement with slow strength growth
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 % It is somewhat surprising that the number of different grinding processes and mill types used by the
