ABSTRACT:
Methods and apparatus for reducing the carbon content of fly ash are disclosed. The fly ash is subjected to an inclined surface having first and second vibratory sources for respectively moving the fly ash from the elevated end of the incline to the lower end and to disaggregate and stratify a high carbon fraction from an enhanced fly ash fraction. The second vibratory source, in combination with the inclined surface, separates the lighter, high carbon fraction while the heavier enhanced fly ash fraction travels toward the lower end of the incline. An air jet and associated vacuum draft pull the high carbon fraction from the incline, leaving the enhanced fly ash portion for use, after removal from the surface, as an example, as acceptable mineral admixture for use in Portland Cement concrete.
