What it doesn't mean is there is a problem with the ball mill of which you seem to assume and in all probability it means the process downstream has been available 95% of the time which is a fair effort considering commissioning is on going still.
By capacity I assume you mean throughput which once again isn't an indication of the mill performance but rather the continuous ramping up of the process during commissioning activities. Mill performance is judged on particle size expressed as P80 (80% passing) and this is difficult to maintain in the start up phase as a mill can only be dry charged to 50% and increased as the product or throughput is increased otherwise increased wear will result and life expectancy between relines decrease with the mill having to be shutdown if the downstream processing ceases otherwise destruction of the mill liners will occur.
Once the downstream process is stable ball mill performance indicators are throughput, load and P80 with first two effecting process costs and the latter recovery based on particle size which will effect flotation/suppression of which a balance is maintained.
Or perhaps instead of writing all that a smilely face may of sufficed
