re Clinker litre weight

Hello BLM,

Yes, high litre weight clinker would certainly tend to be harder to grind since the clinker is more dense. The same is generally true for clinker with low free lime.(<1%).

If you can't reduce clinker litre weight by softer burning, then you could try grinding the raw meal a bit coarser.

Ted.

Dear Ted,

Raw meal residues are allready heigher side I.e. 8 % on 212 mic and 27 % on 90 mic. If we increase further it may lead to increase back end temperatures due to poor heat transfer. Pl comment.

Hello BLM,

The only other thing I can suggest is to reduce the liquid phase of the clinker, which will make the clinker more porous and harder to burn.

Dear all:

If we lengthen the flame to move the clinker cooling zone into the kiln more, we will promote downsizing C3S crystals, thereby achieving ease of grinding.
