Dear all,

Im presently on a job of commissoning a VRM 26.3 UBE japan made.

I have a problem with the vibration of the mill, when i start the mill main drive and set RPM value as 50 % or any % mill vibrates abruptly (upto 15 mm/s) even before reaching the set RPM and even before i could take the feed inside the mill. i request all of you to help me get rid of this problem.

VRM is designed for 20 TPH petcoke grinding.

thanks&regards,

Yathish
