[Prior art]
2. Description of the Related Art Conventionally, when a slurry is manufactured at a construction site or the like, fine powder generated when crushing concrete, cement, and water are agitated and easily performed. In this case, the mixing mixer is carried into the site, and the above-mentioned fine powder, cement and water are stirred by the mixing mixer to produce a slurry. The mixing mixer includes a mixer drum, a chute provided on the upper portion of the mixer drum, a tray provided in an intermediate portion of the mixer drum, a stirring blade provided in a lower end portion of the mixer drum, and water in the mixer drum. And an ejection unit for ejecting the liquid.
[0003]
A powder or the like such as cement is poured from a chute into a tray having an outlet at a lower end, and a liquid such as water is flowed from an injection means into the tray to perform a primary mixing process in which the powder and the particle collide and come into contact with each other. . Next, the powder and the granular material subjected to the primary mixing treatment are caused to flow from the outlet into the lower end of the mixer drum provided with the stirring blade, and a liquid such as water is injected from the injection means into the lower end of the mixer drum. Then, the stirring blade is rotated to stir the granular material and the liquid to perform a secondary mixing process, thereby producing a slurry. The slurry flows out from an ejector tube provided at the lower end of the mixer drum.
[0004]
According to the above-described mixing mixer, cement and the like do not adhere or accumulate inside because the mixing is performed stepwise as in the primary mixing process and the secondary mixing process. Thereby, the concentration of the slurry can be made uniform, mass production is possible, and stirring can be performed evenly (for example, see Patent Document 1).
