Re: Grindiability & Mill Shaft Power

There is no direct relationship between Bond Work Index and the shaft power, just as there is no direct relationship ...

Re: Kiln Control

Do you have any automatic control loops? Is there any water injection responding to changing gas temperatures? Withou...

Re: Kiln Control

If the kiln process is in equilibrium then if you increase the feed rate only the draft will fall as more CO2 from ca...

Re: Kiln Control

I think that the response to such a change in the process would be kiln specific. Nobody can say by how much the back...

Re: aragonite (CaCO3)

I agree with Ted. I doubt if you would be able to detect any affect of small quantities of aragonite on the operation...
