Epifancev 1 A. Nikulin 1 S. Kovshov 1 S. Mozer 1 I. Brigadnov brigadnov@mail.ru 1 National Mineral Resources University Saint-Petersburg, Russian Federation In the article authors investigate extrusion press for forming of peat furnace charge in order to produce fuel pellets. For modeling the behavior of pellets, we used discrete elements method in YADE framework. http://pubs.sciepub.com/ajme/1/3/3/ajme-1-3-3.pdf screw extruders form of the forming and calibrating part of matrix dies discrete elements method press energy output
