In order to develop the design of a press
granulator for processing biomass for pressed biofertilizer
and fuel pellets, a scheme for separating gear pellet presses
by the main features is presented, the main works of scientists
devoted to the investigation of the operation of gear
presses-granulators are analyzed, ways of increasing the
productivity and reliability of press granulators with a ring
matrix, reducing the energy intensity of the granulation
process and labor-consuming maintenance of working
bodies, controlling quality obtained pellets revealed a complex
constructive and technological drawbacks and solved
certain problems by improving the synthesis of the structural
designs pellet presses. The requirements imposed on
the construction of the restraining rings in the development
of a press granulator with an end stop of the wedge-shaped
space are formulated
