limestone particle size in cement mill

  • Understanding Limestone in Cement, Concrete Construction

    Mar 26, 2015· The change is that the specification adds up to 5% limestone. The biggest difference in production is that the limestone is added to the clinker blend before grinding. Because the limestone is softer than the clinker it will grind preferentially, resulting in a cement with a better particle size distribution with less energy. The limestone also

  • Jet mill grinding of portland cement, limestone, and fly

    Nov 01, 2013· The mean particle size of separately ground cement and limestone S-GC85/GL15 was 2.9 μm, slightly lower than the mean particle size of the inter-ground material I-GC85/GL15 which was 3.3 μm. The particle size distributions of separately ground portland cement (GC) and limestone (GL) are shown in Fig. 5 a for comparison.
