pyrites and coal processing pulverizer

Run-of-mine coal from a modern mine may incorporate as much as 60 percent reject materials. Air pollution control often requires partial removal of pyrites with the ash to reduce the sulfur content of the coal. Ash content often must be controlled to conform to a prescribed quality stipulated in contractual agreements. Because of firing ...
