Clinker grindability is determined by quantity of electricity consumed for grinding (kW / ton) under other equal conditions. In cement production entire crushing and grinding process consumes about 85% of the electricity. At the same time 75% of electricity consumed for milling and only 2-20% of them consumed for grinding.

as limestone is much easier to grind than clinker, the fine limestone particles enrich the psd segment where clinker is less present. 1, 4 therefore the filler effect (dense particle packing), the faster precipitation of dissolved hydrates on the higher surface and further effects can improve the mechanical strength of plc up to a limited content …

The authors reported the dense bonding between the uncarbonated clinker and cement matrix as compared to cement matrix prepare without using clinkers. The improvement in interfacial transition zone (ITZ) due to the reaction promoted by the clinker was identified as the main cause of strength improvement.

Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln.

This results in a very dense, very strong tile, but without the extra hardness and water resistance of vitrification. With an absorption rate of less than 4%, red clinker tile is stronger and less absorbent than glazed ceramic tile but is not as strong as fully vitrified tile. Argelith's red clinker has an absorption rate around 2%.

One of these is clinker density, or degree of porosity. Hard burned clinkers (lower free lime) are more dense than clinkers with higher free lime contents. ie they have a lower porosity. This generally makes harder burned clinker harder to grind. This may be one reason why the clinker with a lower free lime is harder to grind in your case.
