2.1 Case study: MVR mill MVR 5000 R-4 It was decided to increase the cement capacity of a plant in North America from 1.250 to 2.200 million t/a. For that re-quirement the plant equipment for pyro-process and grinding process had to be supplemented. To the existing ball mills for raw material grinding, an MVR mill with 5 m table diameter

The cement mill is driven at 16 rev min"1 by a girth gear fitted to the head wall. The girth gear is driven by two pinions, each being connected via a gear box and coupling to a 1560 kW electric motor. The speed ratio between the pinions and the girth gear is 7:1. The girth gear mounting on the mill shell is shown in Fig. 1.
