PURPOSE:To enhance the efficiency in mixing powdery particles by rotating a driving shaft which is arranged coaxially with a vessel, additionally providing an inclined blade or a spiralstrip blade for pushing up the powder to the driving shaft, and eliminating the vortex. CONSTITUTION:The charged pellets Z (A and B) are pushed up along the peripheral wall surface in the direction as shown by the arrow P by the rotation of a ribbon-type agitating blade 3. In this case, since the powder is forcibly guided by a guide plate 6 to the axial center part as shown by the arrow Q' in the surface layer, vortices are not formed on the surface layer, and the surface is practically flattened. Consequently, even the pellets having different particle diameters are moved in the same manner, stagnant parts are not formed, and the pellets are uniformly mixed. The guide plate 6 is appropriately allowed to slide up and down. |
