Comparatively small amounts of energy are also consumed by the ball mill, thickener, dewatering devices, agitators, conveyors, bucket elevators, and similar components. The energy demands of the fans, slurry recirculation pumps, and reheater are calculated separately (as shown in Appendix E for the hypothetical 500 MW powerplant).
As a roller mill, FCB Horomill benefits from the material bed compression which is a source of significant energy saving compared to more traditional technologies. Compared with a ball mill, the FCB Horomill saves up to 50 per cent in energy. Moreover, as it is not an air swept mill the gas circuit is only
