Kilns Question 3
We frequently face with ball formation problem in the kiln for two months. We are studying the case and investigating the parameter changes. What are the possible reasons and the explanation of this phenomenon?

Kilns Question 4
Does better nodulisation mean more consistent size of nodules with less dust or with less large nodules ? What might be wrong if always getting a large portion of large nodules (4-6 inches in diameter), even at 25 per cent liquid phase, which isn't high, and ALm of kiln feed ranging from 1.55-1.75. Kiln is typically run at 3.5rpm. The large nodules are only visible on kiln stops when there is a chance to look into the cooler, before the clinker goes through the crusher.

Re: Kilns
Your chemistry does not sound abnormal and we have discussed the possibility that the large nodules are caused by MgO variation before. A further remote possibility would be Mn2O3 variation where slight increases cause the formation of vary large balls and also take the coating out of the burning zone. However, that is a long shot.
