Try to balance your mill-in-L/S ratio. Try to use a mill-in-density of 1.7t/m3 or 1.75t/m3. Do also inform your operators to monitor the mill load. If it increases with the drop in power draw, they must increase the mill inlet water to flush out the mill rather than to wait until the mill is fully cemented. Good luck.
