We have a ball mill to grind clinker and we have a problem with the cooling system when the temperature is high.
When we use water for cooling in order to control/reduce the clinker temperature, we have no problem but when we use air for cooling after using water the pipe and the nozzle is blocked,so we lost the watertight.
Does anybody have the same problem?
What kind of solution do you recomend?
Thanks in advance
Dear Sirs,
Your water spray nozzle located on counter-current with air flow or not? if yes the problem may be caused by agglomeration of cement on nozzle tip.
The solution may be changing the nozzle position by spraying water in co current with air flow, in front of 2nd compartment and you should take heat balance of your cement mill system

thank you for your answer.
Yes, the nozzle is located on counter-current with air flow produced by a fan, but when we don't use water for cooling, a continuous air flow is running in the nozzle.
We know that the problem is aglomeration of cement on the nozzle tip but we don´t know how to solve the problem because we can´t change the position of the nozzle so we need to find other solution.
Do you know if there is any treatment or coating for the nozzle in order to avoid aglomeration of cement?
Do you know any type of nozzle or system that avoid this problem?
Thank you very much for your time.
Best regards
