Apr 30, 2012 Not only does using fly ash in concrete prevent those heavy metals from being released back into the environment, it also keeps cement makers from mining new raw materials. Advertisement As you might expect, coal ash is a cocktail of toxic chemicals -- it contains the same heavy metals that are found in coal, only in higher concentrations.
not part of an in-line kilnraw mill, used to grind feed to the appropriate size. Moisture may be added or removed from the feed during the grinding operation. If the raw mill is used to remove moisture from feed materials, it is also, by definition, a raw material dryer. The raw mill also includes the air separator associated with the raw mill.
