  • Patent number: 4769200
    Abstract: In order to compound organic materials which are crystalline under standard conditions, these materials, in the pulverulent and/or molten state, are processed in a self-purging, twin-screw extruder in which the screws rotate in the same direction, ejected through one or more narrow passages into a low pressure zone, cooled and comminuted to give particles. In order to improve the pourability and shelf life, the materials are completely crystallized by the time they reach the end of the screws, and are heated during discharge through the narrow passage, in order to form a melt film. Dust-free granules havig a smooth surface can be produced in this manner.
