Regarding of the detail condition, two kinds of techniques are usually adopted in producing manufactured sand, dry way and wet way. Both methods can produce high quality manufactured sand as concrete aggregate. Especially, the dry way can produce not only the manufactured sand used in SMA road surface, but also the powder used in asphalt concrete.
Cooling fans are used to blow cold air to the cooler and to cool the clinker from 1500oC to 100oC. Cooling kiln protects equipment and facilitates quenching the clinker to ensure the important forms of minerals like C3S, C2S, C3A, C4AF stay in it, so that proper clinker quality is maintained.
clinker really have. 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 ef-fect (dense particle packing), the faster precipitation of dissolved hydrates on the higher surface and fur-ther effects can improve the mechanical strength of
