In total, 165 scenarios were simulated. When the mills charge comprising 60% of small balls and 40% of big balls, mill speed has the greatest influence on power consumption. When the mill charge is more homogeneous size, the effect of ball segregation is less and so the power consumption of the mill will be less affected.

SikaGrind® FOR VERTICAL ROLLER MILLS 3 In a ball mill, the particles are ground by repeated impact forces. The material needs usually more than 20 minutes from mill entrance to outlet, uncountable impacts take place on this way. Depending on the efficiency of the separator and the Grinding Aid, agglomerates of fine particles are rejected and ...
