  • Patent number: 6907994
    Abstract: There is provided a process for converting wet fly ash into a useful product such as cement replacement or industrial filler. A first amount of wet fly ash is provided. The wet fly ash is fed into a mixing chamber. An amount of aggregate, such as stone, is provided. The aggregate is also fed into the mixing chamber where the wet fly ash is mixed with the aggregate. The mixed wet fly ash and aggregate is fed into a drying chamber where the mixture is heated, thereby drying the fly ash and heating the aggregate. The heated aggregate is separated from the fly ash. The heated aggregate is fed back into the mixing chamber. A second amount of wet fly ash is added to the mixing chamber where is it mixed with the heated aggregate. The heated aggregate assists in drying the second amount of wet fly ash. Once in cycle, the process is continuous.
