Clinker grindability
What will be the expected effect of clinker free lime and alite & belite average grain size(micron) on clinker grindability or Bond's work index?

Re: Clinker grindability
Mr.David,
Could you explain logic behind your replied perception? Ono method of clinker characteristics ranked that clinker belite size 25-40micron as excellent clinker and 5-10 micron as poor clinker.I would also like to know views of other forum members.

Re: Clinker grindability
Mr. Sahu.
The Ono version depends on wether there are belite clusters in clicker or not. As I know belite formation in clusters (even with smaller crystals) will make clinker harder to grind compared to clinker with well-distributed individual crystals. If the raw meal is well mixed and there are no large quartz grains in meal, the belite cluster formation is less probably.
I can point you the enother case when clinkers' belite crystals are: 1) well distributed but 5-10 microns (a little underfired clinker) 2) also well distributed in 25-40 microns. What you think which of the clinkers, in equal conditions easy to grind? And what Ono wrote about the case?
