2. Status of grinding technology The comparison of various grinding methods, viz., close-circuit ball-mill, roller press (in semi-finish mode in combination with BM and in finish mode) and vertical roller mill (VRM) is shown in Fig. 1. The most recent developments have been the use of VRM and RP (in finish-mode) for slag and clinker grinding.

Re: Roller Press. Slag and clinker can be ground together in a roll press. The main problems are associated with the moisture content of the slag. You need to have some kind of drying arrangement in a V-separator or such-like equipment. The output of a cement mill when grinding slag will depend on the fineness of grinding the slag and the type of cement mill, i.e. ball mill, open circuit 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.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
