clinker ball formation in pre burning zone of the rotary kiln. We have two kilns in our unit. In both the kilns, we are facing very big unshaped clinker coating coming from kiln inlet to pre burning zone and disturb the steady kiln operations. Sometime, this very big coating block the entire cross section of the kiln at the pre burning zone starting.
