White cement clinker bleaching process. In our white cement plant, we use the combination of spray fog quenching and grate cooler strong wind quenching to bleach the clinker out of the kiln. The principle of this method is to reduce the trivalent iron in clinker to bivalent iron, so as to improve the whiteness of clinker.
