Pulverizer Vibration Issues

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 that “bump”

2012-3-1 · Coal samples obtained from Wanbei (WB), Pingxiang (PX), Liupanshui (LP), and Datong (DT) mines were pulverized, using either a vibration mill or a ball mill, to different degrees of fineness. The effect of the different grinding methods on the mineral distribution within the pulverized coal was investigated by using proximate analysis, particle size analysis, and float-sink tests.

COAL PULVERIZER DESIGN UPGRADES TO MEET THE

2010-7-27 · The counter pressure reduces the noise generated by the mill and is adjustable depending on the coalproperties and required coal fineness. During operation, both pressures are adjusted proportionatelyto the feeder speed by means of pressure control valves to achieve an optimized grinding forcecharacteristic throughout the mill load range. During mill startup or shutdown, a higher pressure isapplied on the piston bottom face than on the piston ring face to eliminate mill vibration or rumbleby reducing the grinding force against the mill table. With sufficient high pressure on the pistonbottom face, the rollers can even be lifted off of the grinding table segments, which results in asignificant wear reduction between the rollers and grinding segments, as well as minimal mill torquerequirement during mill

2012-11-17 · Specifically, fineness is a measurement of the percentage of a coal sample that passes through a set of test sieves usually designated at 50, 100, and 200 mesh A 70% coal sample passing through a 200 mesh screen indicates optimum mill performance. The mill wear and the power consumption are increased if the 70% value is exceeded. Values lower than 70% mean higher carbon loss and increased fuel consumption. In addition, coal
