Studies on coating and ring formations

Build ups and ring formation in cement rotary kilns has been known to induce operational instability and restrict gas/material flow to the point where kiln has to be stopped. Studies on coating and ring formation are taken up as a part of the diagnostic studies for minimizing/ eliminating coating and ring formation in cement rotary kiln system. The studies involve chemical and mineralogical evaluation of raw materials being used by the plant, evaluation of raw mix from periods of normal operation as well as from periods preceding ring/ coating formation and chemical and mineralogical evaluation of coating and ring samples. Recommendations have been found important on modifying the raw mix designs for avoiding coating/ ring formations
