Pulverizer - Wikipedia

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 ...

A Comparison of Three Types of Coal Pulverizers

Properly sized pulverized coal exits the classifier into coal piping for transport to the furnace. Oversized pro- duct is, however, separated and returned to the mill for further grinding. There is minimal metal-to-metal contact of the grinding elements in the BTM resulting in very little wear and low maintenance. The mill heads are cast integral with trunnions which are supported in special ...

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.
