In a process reactor and a method for the electro-dynamic fragmentation of lumpy mineral materials by pulsed high voltage discharges, including a reaction chamber with a funnel-like bottom having a central outlet, an axially movable high-voltage electrode extending from the top into the reaction chamber and having a front end disposed opposite the central outlet where another electrode which is at an electric reference potential is disposed, the outlet converges into a tailback tube below which a transport unit for the controlled removal of the processed fragmented material sinking down through the tailback tube is disposed, a material supply arrangement extends to an opening in the wall of the reaction chamber and a material flow blocking structure is disposed in the reaction in front of the material inlet opening for controlling the material admission to, and the fill level in, the reaction chamber.
