Vertical Mixers
amixon® vertical mixers have vertically mounted agitator shafts. They can also be described as slowly rotating shear mixers. Their mode of action is based on the upward motion of goods in the periphery of the mixing chamber and the downward flow of goods in the centre.
In this respect, all the particles in the mixing chamber are in relative motion to the environment. Permanent changes of the particles, that are taking place inside the vertical mixer, result in the highest mixing qualities. Those mixing results are not further improvable in practice. The peripheral speed of the SinConvex® mixing tool inside the vertical mixer is usually only 1 m/s to 2.5 m/s.
As the flow of the solids takes place very slowly, there is no separation, neither by gravity, by centrifugal effects, nor during discharge. Mixing times in a vertical mixer are only 2 - 6 minutes despite differing properties of the components.
Those could be for example particle size, particle shape, bulk density, moisture levels, flow properties, liquid, solid or gaseous state, etc. The filling ratios can vary from about 10% to about 70% of the gross volume.
