PROBLEM TO BE SOLVED: To provide an apparatus and method for fluid mixing having a high mixing efficiency, and easy to remove impurities even if the impurities are caught. SOLUTION: Liquid or powder is added to liquid flowing in a pipe 1 from a pipe 2, then the liquid is made to pass through a plurality of half-opened ball valves 3A-3C for mixing. Each of the ball valves 3A-3C has an angle differenceθin the phase around an axis. A static mixer of a complicated structure is dispensed with and favorable mixing can be obtained. When clogged with impurities, opening of the valve can release the impurities. COPYRIGHT: (C)2011,JPO&INPIT
