PURPOSE:To enhance mixing and treating capacities and to decrease motive power of operation, by providing both an impeller which is provided to the inside of a mixing chamber and rotated with a driver and a gas feeder connected to a gas chamber. CONSTITUTION:An impeller 7 is provided parallel to an air supply plate 2 and preset so that the center of its rotation crosses the upper and lower flow of powder. The impeller 7 performs action vanishing a vortex wherein the impeller 7 is interlaced to the circulating flows and thereby made to rotary flows G accompanying a complex fluctuation and these are made to one kind of dead part easily caused in convection and circulation of powder and the composition of powder is changed by accompanying separation phenomena. Furthermore strong shearing action is given to powder by the rotation of the impeller 7 and even fluid having flocculating properties vanishes its flocculating properties and is fluidized and migration, agitation and shearing action are fully given to powder as a whole and a mixed product excellent in precision of ratio and degree of mixing is obtained. |
