The slurry batcher mixer of the present invention includes a mixing vessel having a pair of vertical side plates with a trough supported along the length of the vessel between the side plates. A ribbon type screw conveyor is mounted in the trough and extends the length of the mixing vessel, and is connected to a reversible drive motor to selectively rotate the screw in a first direction to convey material to a discharge port, or in the opposite direction to provide a positive thorough mixing of the contents of the mixing vessel. A source of fly ash, cement, and water is provided to the mixing vessel, and a pair of spray bars are mounted on the side plates with nozzles directed towards the screw, to spray water along the length of the screw.

[ I claim:] [1.] A batching and mixing apparatus, comprising:a mixing vessel having first and second ends, a pair of generally vertical side plates extending between the end, and a trough supported along the side plates and extending from the first end to the second end;a cover plate extending across a top of the mixing vessel to enclose the top of the mixing vessel and including a first inlet port therein for permitting the flow of a first material comprising a dust-producing particulate into the enclosed mixing vessel;a discharge port formed in the trough proximal the second end, with an operable discharge gate therein, operable between an open position and a closed position;a ribbon type screw conveyor operably mounted in the trough and extending from the first end to the second end of the trough, said conveyor including a spiral flighting with an outer edge and an inward edge, the outward edge in slidable engagement with the trough;an elongated spray bar mounted on one of said side plates along a length of the mixing vessel substantially from the first end to the second end, the spray bar having a plurality of spaced-apart spray nozzles thereon directed towards the screw conveyor; whereby a liquid sprayed through the spray nozzles moistens the first material and reduces the production of dust; anda reversible drive motor connected to the conveyor for selectively rotating the conveyor in first and second directions.
