Abstract

Die Presse zum Herstellen von Hohlbriketts aus einer Biomasse weist einen oszillierend angetriebenen Stößel (1) auf, der gegenüberstehend eines Preßrohres (2) angeordnet ist und dem eine beschickbare Spänekammer (21) vorgeschaltet wird. Der Stößel (1) umfaßt einen in Preßrichtung axial vorstehenden Verdichtungsdorn (8), der einen kleineren Durch­ messer als der Stößelkopf (12) aufweist, sich ins Preßrohr (2) erstreckt und mit dem Dorn (8) einen in radialen Richtungen beaufschlagbaren Verdichtungsraum bildet. The press for making hollow briquettes from one Biomass has an oscillating pusher (1) on the opposite of a press tube (2) arranged is and upstream of a loadable chip chamber (21) becomes. The plunger (1) comprises an axially in the pressing direction protruding compression mandrel (8), which has a smaller through knife than the plunger head (12), into the press tube (2) extends and with the mandrel (8) in radial directions pressurized compression space forms.
