Pulverizer Vibration (Rumbling) - Innovative Combustion Technologies

There are two recommended courses of action to alleviate the “rumble”. The first, and preferable, is simply to raise the minimum load point at which the pulverizer is removed from “service”. Higher coal flows will result in lower fineness. The second, which is rarely needed, is to install small irregularities in the grinding ring.

Breakage and separation mechanism of ZGM coal mill based on .

The new feed drops on the rotatable grinding disc of the coal mill by gravity and mixes with the circulating load. When the feed is crushed into the pulverized fuel by squeezing and grinding, the pulverized coal is dried by the primary hot air and then transported into the coarse powder separator. The qualified fine coal is.
