Separate grindings versus intergrinding - Sintef

Jul 17, 2007 . The main difference between intergrinding and separate grinding of a multi-component cement is that during intergrinding the different components interact with one another. The interactions between the constituents are mostly due to the relative difference in grindability. When discussing the grindability.

Portland cement replacement: within-mixer or factory-blend? - The .

Blast-furnace slag is harder to grind than Portland cement, and inter- grinding results in the cement being ground finer than the slag, which is the opposite of what is normally desired for strength-gain reasons. Best practice for factory blending is to grind the blast-furnace slag and cement separately and subsequently blend.

are filled with hot cement. Mostly adsorption of grinding aids is revers- ible. As the binding forces are small at the usual mill operating temperatures (80-120 °C), adsorbed molecules can desorb from the clinker surface. The boiling points of liquids correlate with the inter- molecular interactions (“strength of the adsorption.
