The mechanical granulation eliminates the typical granulate
defects such as, for example, nutshell structure. The ability to granulate
follows from the way in which the material moves which is
similar to the material stream in the disc pelletizer, the difference
lies in the fact that in the intensive mixer the granulation is much
faster and facilitated by the mechanical impact of the mixer and
the movement of the pan correlated with the direction of the material
stream formed by the high-speed rotor. In comparison to the
disc or drum pelletizer, granulation in the intensive mixer runs in
the whole volume of the processed material and does not require
such a complex control [13].
During the tests, starch and glycerin were mixed and granulated
in Intensive Mixer Eirich R02 (Fig. 1). Starch and glycerin were mixed
in ratio 75 wt.% and 25 wt.%. Mixing parameters: agitator rotations
3000 rpm, pan rotations 120 rpm, mixing time 60 s. Granulation
