In raw grinding, a ball mill with a high efficiency separator is used to achieve uniform particle size in raw mix for the next stages of the manufacturing process. At the Cement Grinding Stage, 90 – 95% of the clinker is mixed with gypsum and ground in a Cement Ball Mill to produce quality cement OPC 43 and OPC 53.
My first impression is that the log formula would be based on an assumption regarding the size distribution at the entrance of the separator. I would guess it represents the ratio of fines actually collected to the amount of fines that could be collected. This would justify the word "efficiency". Calculations might be done assuming a Rosin ...
