High-efficiency cement grinding - CemNet
This is called a combi-grinding circuit. The main feature of such a system is the pre-grinding of cement clinker in the POLYCOM and a final grinding in the ball mill. The specific power consumption compared to a ball mill cement grinding is significantly lower and additionally paired with a 30 to 40 per cent increase in output.

What is the efficiency of ball mills? – handlebar-online
What is the efficiency of ball mills? According to this definition, given that the energy utilization in a ball mill is between 1×10−3 and 4×10−3 m2/J, and that the crack resistance value is between 30 and 60 J/m2, the theoretical efficiency of the ball mill should be in the range of 1.5–12%.
