In an aeration enclosure in which the arms are connected, the enclosure has a bubble shear assembly with a ratio H / D of height H to diameter of between 0.5 and 5.0, and a ratio W / r of front width W to maximum arm length r of 0.1 or less. The system has a bubble shear device positioned perpendicular to each other on a vertical rotating shaft such that the maximum arm length R is at least 25% of the diameter D of the enclosure and the ratio of the arm front width W to the shear vertical gap S is between 0.005 and 0.04. The outermost radius at least 40% of the maximum arm length so that gas bubbles rising into the solid mixture pass through the area of the substantial portion swept by the bubble shear device With at various radial positions, and which it was injected into the aeration gas bubbles in the set of closed bottom upward, rotating the vertical shaft in order to provide a constant level of turbulence intensity at the height of each bubble shearing device while 1000U.S. Maintain a shaft power density of less than 1.5 SHP per gallon of containment capacity, repeatedly shearing gas bubbles rising by the rotary arms into small gas bubbles and continuing to infuse at least 15 gas mixtures for at least 15 minutes of mixture retention. And a method for continuously aeration of a high solids concentration of water-based plastic liquid-solid mixture having a total solids concentration of at least 2.5% by weight in an aeration enclosure characterized by rotating. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
