PURPOSE:To increase mixing speed by providing a mixing container with blades of different types in the inside. CONSTITUTION:Blades 28 which are all directed in the same direction toward a mixing shaft S1 and blades 28r and 28c which are all directed in the opposite direction, blades 29l and 29c which are all directed in the same direction toward a mixing shaft S2 and blades 29r which are all directed in the opposite direction, blades 30l and 30r whose directions toward a mixing shaft S3 are opposite from those of the blades 29l and 29r and blades 30c which are directed in the same direction as the blades 29r, blades 31l-31r which are all directed in the same direction toward a mixing shafts S2 and S4, and blades 32l-32r which are installed in staggered positions with a phase difference of 180 deg. toward a mixing shaft S5 are provided in a mixing container 13 equipped with an intake 13b and an outlet 13c. In this mechanism, the charged concrete-making aggregates are raked together toward the center, sheared, pushed in and out in the direction perpendicularly to a passage 13 and also overturned repetitively so that these aggregates can be mixed quickly and uniformly. |
