摘要 |
An apparatus and process for pulverization of polymeric material having a multi-component screw disposed within an elongated cylindrical housing. The multi-component screw has an independently rotatable extrusion portion and an independently rotatable pulverization portion. A cooling means is provided to maintain the fine powder material produced during the pulverization process at a desired temperature. In one embodiment of this invention, a second multi-component screw having an independently rotatable extrusion portion and an independently rotatable pulverization portion is disposed within the elongated cylindrical housing.
