# ball mill filling level counting

### Efficiency and grinding media filling levelIEEE

Since delivery time for parts to repair the damaged drive was lengthy a decision was made to reduce the charge in the ball mill from approximate 32 filling level to a point low enough to allow the mill to be operated with the single remaining drive. Surprisingly the result was a minimal loss in production with a significant gain in efficiency.
