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. Experts may kindly suggest solutions to solve this problem

Dear Mr. T.Rajgopal,
Possible reasons for ring & ball formation,
Raw mix design,
High coal ash %
High liquid phase
Quality/ condition of refractory
High alkali feed
Burner pipe condition
Cooler condition
But to study all above reasons we have to run our kiln for 20 ~ 30 days continuously, we have technique to remove big clinker balls without stopping the kiln.

Hello Gopal
You mentioned that coating comming from the inlet side...{But Your subject is different}
so must check the coating status at mixing chamber and riser duct and if you have inline calciner must take inspection at venturi area.......
if your both lines facing same problem then lab must take serious action about it, may be your x-ray calibration is out of order
