Abstract
A method of suppressing dust generation emanating from cement clinker dust by applying a foamed dust control treatment thereto. The foam is provided with an effective defoaming agent which, upon slurrying of the clinker and other ingredients (e.g., sand, gypsum, aggregate) to form the desired mortar, inhibits foam formation in the mortar, thus not significantly increasing air entrapped in the slurried mortar.
Claims14
Method comprising suppressing dust generation emanating from cement clinker by applying foam to said clinker, said foam including an agent which exhibits antifoaming properties in cement mortar, grinding said clinker to form cement, and slurrying said cement with other ingredients to form slurried cement said antifoaming agent inhibiting foam formation in said slurried cement so as to not significantly increase air entrapped in said slurried cement.
Method comprising suppressing dust generation emanating from cement clinker by applying foam comprising water, surfactant and oil to said clinker, grinding said clinker to form cement, slurrying said cement with other ingredients to form slurried cement and inhibiting foam formation in said slurried cement so as to not significantly increase air entrapped in said slurried cement.
