Abstract: A discharge nozzle connected to the outlet of an extruder is built wedge-shaped in vertical longitudinal section and comprises a lower housing part and an upper housing part. The upper housing part is adapted to be swung open by being pivoted around a pivot axis, thus causing the nozzle to open. This opening of the nozzle occurs under the influence of a control and actuating member, as soon as a predetermined value of twisting moment, pressure or temperature is exceeded. The nozzle discharge opening has shutting locking bolts associated with it, adapted to shut off the discharge channels of the discharge opening of the nozzle. The discharge nozzle may be used to advantage for the continuous processing of electrode material.

Abstract: The continuous production of electrode material consisting of pitch, coke dust and coke particles of variable sizes comprising the steps of mixing and kneading the components in a horizontally arranged mixing and kneading device. An extruder is provided at the output end of the mixing and kneading device and connected with the same by way of a vertically arranged chute. The rotation of the extruder is controlled by a sensoring device provided in the vertically arranged chute. A lateral ejector orifice provided in the chute is shut off by means of an ejector flap subject to the influence of a control device; this in turn also exerts its influence on the extruder drive. The forming operation is completely separated from the mixing and kneading process, so that no mutual influencing can take place.
