- Abstract
The Vertical continuous mixer has number of mixing units connected in series. When using this mixer in the vertical way, mixing work can be done under gravity force only with the new modified mechanism of inter-particle collision and impact. The mixing process inside the vertical continuous mixer is totally different from that of existing mixers. The aims of this paper are to clarify the mechanism of mixing process of the vertical continuous mixer with gravity and to obtain the useful information on the design of a high-performance vertical continuous mixer with help of the visualization technique. The results of this study indicate that it is very important that the accumulation time of materials through mixing units is long and that the fluctuation of velocity of materials falling and the fluctuation of angle of materials falling are large as long as the blockade of materials does not happen in order to increase the mixing efficiency of vertical continuous mixer.
