Grinding energy was approximately 50 per cent of the ball mill and the drying capabilities allowed direct processing of materials of up to 20 per cent moisture content. The main energy issue was the high power consumption of mill fans, with pressure drops of 100mbar not uncommon with high nozzle ring velocities (>70m/s) and internal mill ...
The basic design of the mill is as for raw grinding, however, the mill does not have the built in separator and the grinding tools are adjusted for clinker grinding. The material fed to the tube mill is £ 3 [mm]. Possible configurations are (Figure 12): Closed circuit with recirculation; Comparable with roller press and slab recirculation.
