A coal mill is the important auxiliary equipment for coal-powder furnace. It has three methods to crush the coal lumps and to grind them into powders, that is, crushing, impacting and grinding. Coal mill is used to grind, pulverize and dry coal before the coal is transmitted the boiler. The coal is fed into the coal mill via an inlet pipe so ...

Since the first application using an MPS mill to process pulverized coal in Germany in the mid 1960s, there have been over 2,000 different MPS mill installations operating in coal-fired power plants worldwide. As one of the most popular coal pulverizers in the utility industry, the MPS mill was first introduced into the US in the early 1970s.
To summarize the coal mill controls, they may be divided basically into two major categories:. 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel.

Coal Mines and Canaries - The first real form of gas detection was the canary in a coal mine.Canaries were used because they would fall victim to the effects of carbon monoxide and other poisonous gases well before miners, and as a result, alert the miners to changes in the atmosphere of the mine. The miners were betting their lives, and the lives of the rest of the miners, on the bright ...
Coal from travelling belt of raw coal feeder drops in central feed pipe ( connection between Raw Coal Feeder and Mill). After coal reaches Mill bowl grinding started and hot air also been given to make the pulverised fuel dried enough to classifier chamber. The portion of the coal which cannot be grinded finds its way to mill reject.
