Materials Of Construction For Coal 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...Today, it is estimated that the global steel industry used about 2 billion tonnes of iron ore, 1 billion tonnes of metallurgical coal and 575 million tonnes of steel scrap to produce about 1.7 billion tonnes of crude steel. Recycled steel (also called scrap steel) is one of the industry's most important raw materials.

The recycled coal can be used for power boiler fuel, washed gangue can be used for construction materials, and pyrite can be used as chemical raw materials; 4.
