Understanding Line in Cement| Concrete Producer | Cement .

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

The cementitious binder is manufactured by grinding Portland cement clinker with calcium sulphate with or without additional supplementary cementitious materials . The energy consumption needed to heat the material to this high temperature combined with the chemical decomposition (decarbonation) of line which.

influence of particle size

Grinding line together with clinker is a common way in the cement manufacture to prepare blended cements. Due to the soft nature of the line compared to that of the stiff nature of the clinker, the resulting line particle sizes are significantly smaller than those of the clinker. The small size of the line.
