3.2.2. Approach Used for Clinker Grinding. Initially, a control mix was prepared by grinding 6 kg of materials without any GA until achieving a Blaine fineness similar to that obtained from industrial testing, that is, 3850 ± 75 cm 2 /g. The percentages of clinker, pozzolan, and gypsum in the ground mix were maintained similar to those …

9]. Limestone is softer than clinker, thus requires less energy in grinding therefore, increasing the percentage of limestone in PLC preparation will also reduce the energy demand. Clinker is a multiple phase material, shows significant variation in its properties due to changes in its chemical composition, mineralogy and microstructural character-

The ASTM C150-21 standard has maximum limit values for the amount of iron in type II (Fe 2 O 3 ≤ 6.0 wt%) and type IV (Fe 2 O 3 ≤ 6.5 wt%) clinkers, but such limiting values are not present in EN standards. ... 3.2.3 Clinker grinding. Grindability of the products, excessive wear of the equipment and energy efficiency are among the main ...

Finally, a study of clinker's grindability enabled us to evaluate the probability of grinding of these samples. In all cases, the best clinker is the one that has a vintage's fineness close to 13 ...

Grinding of clinker is the last and most energy-consuming stage of the cement manufacturing process, drawing on average 40% of the total energy required to produce one ton of cement. During this stage, the clinker particles are substantially reduced in size to generate a certain level of fineness as it has a direct influence on such

The hardest clinker takes about 80% more power than the softest one [2]. Furthermore, different fineness requirements result in higher energy consumption. Clinker grindability is the measure of the ability of a clinker to resist grinding forces. It is used to estimate the energy requirement for grinding the clinker to a given fineness.

Experimental Blaine fineness values are greater than calculated values meaning that during intergrinding different ingredients do not show the same behavior as in the case of separate grinding. These findings explain that clinker particles have an abrasion effect thus an extra grinding effect on colemanite particles.
