re Pozzolan addition directly into Cement Mill
Hello Shastri,
How hard is the pozzolan you are using?
What is the top size of the pre-ground material from the roll press?
Is the mill a two compartment ball mill?
If it is two compartment, what is the top size of the balls in the first compartment of the ball mill? If the top size of the balls in the first compartment are much less than ~90mm you will have trouble grinding the pozzolan.
If the mill is a single compartment mill, which I suspect it is, I think you will have trouble effectively grinding the 25.4mm pozzolan because the top size of the material exiting the roll press is most likely much smaller than this.
Regards,
Ted.
