re Cement Mill Grinding Media. These are just the basics if you want to accurately do it you have to fill it up to 80% BC and then do a longitudinal sieving and then correct the BC based on the results. The biggest ball determination is explained and it is based on material hardness and biggest size. Let me know if you need more info.
If a substantial difference is seen in fineness but the strengths have remained the same, it is indicative of some change in the cement production. It may be related to clinker chemistry, kiln operation, clinker cooling, finish mill operation, use of a secondary clinker source, sulfate content, or a completely different cement source.
