Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is …

coal mining, extraction of coal deposits from the surface of Earth and from underground.. Coal is the most abundant fossil fuel on Earth. Its predominant use has always been for producing heat energy. It was the basic energy source that fueled the Industrial Revolution of the 18th and 19th centuries, and the industrial growth of that era in turn supported the large-scale exploitation of …

The pulverised coal from a mill is transferred through alternative flue gas to the cyclone separator, where the coal is separated and flue gas is sent back to the mill. The coal is then supplied to the burner feeder from where it is mixed with primary air and supplied to the burner for the combustion. Advantages. Good control on coal fineness.

The ATOX® Coal Mill can grind and dry raw coal with up to 25 percent moisture level. By adjusting the gas flow stream with the nozzle, you can deal with more 'sticky', high-moisture feed materials. There is an oversized nozzle ring and separator that is available to make this adjustment. A fine operation.
