HYDROMIX INC.

mechanical mixing machines and conveyors used to implement a method of mixing cementitious material, liquid, and aggregate using a cementitious material/liquid premixer to form concrete; this method of mixing includes - dispensing cementitious material through a material outlet; receiving the cementitious material into an enclosed screw conveyer assembly and moving the cementitious material with said screw conveyor toward a conveyor outlet; introducing liquid into the screw conveyor so as to deposit a quantity of the liquid into the cementitious material as the cementitious material is moving toward the conveyor outlet; agitating and mixing the liquid and the cementitious material together by movement of the screw conveyor, thereby forming a flowable slurry; and discharging the flowable slurry from the conveyor outlet into a final product mixing chamber where aggregate material will be introduced
