Thanks a lot for the reply but my experience is just opposite with respect to free lime in clinker & mill production. Some time back we faces a lot of problem of high free lime in clinker ( increased to 3.5% from 1.5%) & we observed that our both mill productions reduced by 15-20% . One mill is open & the other is closed ckt.
