Benchmarks for the finish line
Following Hans-Jorgen Nielsen’s “Ceramic Strengths” article in ICR’s June issue, Dr Michael Clark examines the potential energy-saving differences between milling systems used for cement finish grinding.
Using ceramic grinding media in ball mills results in overall energy savings
ICR June had an interesting article on “Ceramic strengths” by Hans-Jorgen Nielsen of LNV Technology PvT Ltd (Sinoma). The article looked at how unit electricity consumption in cement finish grinding with a roll press and ball mill combination with the ball mill charged with ceramic media can be lower than with a vertical roller mill (VRM), concluding that more cement companies will opt for this solution for cement grinding.
Equally as interesting was the detailed breakdown of unit electricity consumption in cement grinding with different technologies.
