Abstract

The jacket material of welding rods is removed and processed for reuse, and the rods are cleaned and processed for reuse by delivering the jacketed rods to a ball mill, grinding the jackets from the rods within the ball mill by oscillating the jacketed rods in the environment of equally long cylindrical grinding bodies while holding the rods and the grinding bodies against axial movement and in generally parallel disposition with respect to one another. The detached jacket material is conveyed continuously from the grinding chamber and further comminuted, the transport of the ground material being supported by flowing a fluid through the grinding chamber. The fluid may be a gas or a liquid and may contain a chemical reacting agent for an after treatment. The fluid may advantageously be circulated, freed from the solid material transported thereby, regenerated and/or heated. Both neutral and chemically reacting fluids may be alternately employed, depending on the particular materials involved.
