When cement clinker is ground using grinding aids a ...

When cement clinker is ground using grinding aids a narrower particle size range is generated, as the percentage of very fine particles, which only influence the setting time, is reduced. This is why the strengths at equal Blaine values are higher than when grinding without grinding aids. With closed-circuit grinding plants it was also noted that cement ground with heavy circulating loads ...
