The invention discloses a multiple-kinetic-energy mixer for building. The multiple-kinetic-energy mixer for building comprises a mixer body; a feeding opening is fixedly connected to the top of the mixer body, round balls are fixedly connected to the tops of the left side and the right side of the mixer body correspondingly, and transporting plates are movably connected to the outer walls of the left side and the right side of the mixer body; and a base is fixedly connected to the top of the mixer body, rolling wheels are fixedly connected to the bottoms of the left side and the right side ofthe base, a discharging device and a hook device are fixedly connected to the observe side of the mixer body, and a first discharging opening and a second discharging opening are formed in the left side and the right side of the observe side of the discharging device correspondingly. According to the multiple-kinetic-energy mixer for building, through cooperation of a controller and a pusher, a cutter blade and cutting gears are fixedly connected to the left side of the controller, so that the cutting gears conduct opening cutting on cement bags, then the cement bags with the openings being cut are pushed into a feeding device through the pusher, and feeding to the mixer body is achieved accordingly.
