Re: vertical mill

The efficiency of a vertical mill depends on the stable bed formation under the rollers for grinding. If the feed is too fine then there is no stable bed, and hence the vibration. as regarding the mill DP it is obvious due to the mill getting empty.

Re: vertical mill

the mill is filled and DP is going to be very high in short time, and the layer thickness decrease so we can't feed the mill to it's nominal capacity. does the problem in separation inside the mill?

Re: vertical mill

Vibration is mainly due to unstable grinding bed.To have a stable bed,please consider to increase the dam ring height if possible.Sometimes water spray in grinding table also helps to have a stable bed.
