Methodological Aspects of Theoretical Determination of the Kmz-2 Extruder Performance

The purpose of the research is reducing the energy consumption of the KMZ-2 extruder, which will improve its performance. The research tasks are to achieve the purpose: to consider the sunflower seeds compression in the working chamber of the KMZ-2 extruder to obtain sunflower cake; to consider the material that exits through the matrix dies; to consider the movement of the pressed material in the matrix die of the KMZ-2 extruder. On the basis of the conducted research the following conclusions were made: stabilization of the extrusion pressure of the processed material to produce a sunflower cake at the end of the process leads to its friction force reduction on the KMZ-2 extruder auger shaft; the outcoming expression on the theoretical research results allows to change the KMZ-2 extruder capacity when processing the material and with increasing the extrusion speed its performance increases accordingly.
