Cement Kiln to Lime Kiln I want to know if some factor of conversion exists for a cement kiln of two stages converted to oven of lime (without use of the tower). For example, if the cement kiln production is 1000 Tn/day, which would be the lime kiln production? 138 posts Re: Cement Kiln to Lime Kiln As a quick guess, I would be inclined to say that the calcination rate would be the same, that is the same quantity of CaCO3 should be calcined. However there are reasons for some difference too. - Removing the tower would imply that the preheating should occur in the rotary kiln.
