ABSTRACT
The paper presents an analysis of structural solutions for plant materials granulator working systems. For the considerations, the criterion of material uniform dosing and its distribution on the surface of the matrix in the granulator working system was adopted. The analysis shows that the working system "flat fixed die–rotating set of compacting rolls" and "annular rotary die–immovable set of compacting rolls" is the best solution ensuring the distribution of compacted material on the working surface of the die. This results in a stable load of the granulator drive system, including increased bearing life and reduced tribological wear of the die and compacting rolls. An innovative solution of the material dosing system was also presented.
