Ball Mills

Ball Mills

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.

An air classifier is an industrial machine which separates materials by a combination of size, shape, and density.. It works by injecting the material stream to be sorted into a chamber which contains a column of rising air.Inside the separation chamber, air drag on the objects supplies an upward force which counteracts the force of gravity and lifts the material to be sorted up into the air.

In addition to raising the coal temperature inside the mill for drying and better grinding, the same air works as the transport medium to move the pulverized coal out of the mill: it travels through the annular space between the fixed trunnion tubes and the rotating hot air tube onwards to the classifier. Coal-laden air passes through double cone static classifiers, with adjustable classifier vanes, for segregation into pulverized fuel of the desired …
