Dear Expert,

Last kiln stop (few weeks ago), we found big sowman at "R" position of bull nose. After we run the kiln, now the snowman appears again at same position in the bullnose. Our clinker quality, SM 2.35 & liquid phase 27.5 % , SO3 at hot meal very high (more than 4 %). Can someone share the experience related to problem?

With thanks,
