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.
Answer (1 of 2): Mills are defined by the type of grinding media (balls, rods or the ore itself), their physical dimensions (length and diameter), and power input, not by the material that they are used to process. The selection of a particular mill for a particular purpose depends on the physi...
