Good Morning all,
My experience with grinding clinker with limestone to produce OPC resulted in the coating and blocking of the ball mill centre diaphragm. Can someone explain to me why?
Responses will help me greatly going forward.
Thanks

You should check set regulator Gypsum moisutre and its feeding rate,which can be the cause of coating inside the mill.
Hello Shastri,
100oC seems a bit low. Normally you should try to keep the mill outlet temperature at between 110 and 115oC. Have you tested the water content of the cement blocking the diaphragm? If you use water sprays they may not be atomising correctly, causing localised buildup of moist cement.
Also, have you considered a grinding aid? Grinding aid will reduce agglomeration of cement particles and facilitate easier flow of material through the diaphragm.
Regards,
Ted.
