cement plant coal mill fire extinguisher uses,the cement/lime industry has had to search for a way to reduce costs and this has resulted in the near standardization of coal-fired (or coke) systems for firing up the kiln. these systems are indirect-fired, where coal is crushed in mills/pulverizers, then classified by size for collection as a fuel or dust through a heated air conveyance network..cement plants coal,london coal gas production began in 1813 and by 1842 was producing 300,000 tons of coke a year, so coke was also readily available, and, being essentially a waste product, was cheaper than coal. early cement plants used coal for drying slurry and for power generation, and coke for kiln burning. per tonne of clinker produced, consumption was.
