An Industrial Comparative Study Of Cement Clinker

May 01, 2012 The reduction ratio was about 335 for the HPRM circuit for grinding the clinker feed with a median size of about 6 mm down to a cement product of 18-m median size. This large difference between the reduction ratios must be the main reason for having lower specific energy consumption in the ball mill circuit despite the well-known fact that size reduction in
