Apparatus and process for granulating dry powder materials |
摘要 |
Uniformly sized granules are formed using the present extruder and granulation process. The extruder contains a spiral worm screw for guiding a granulation material to an apertured plate. The spiral worm screw is rotated within a chamber and is formed from a guiding slant which terminates at a blunt edge near the apertured plate. The blunt edge rubs the granulation material against the apertured plate which softens the material foming a semi-solid material. The semi-solid material is then gently pushed through the apertured plate using just the required pressure. The granules are formed when the semi-solid material hardens after exiting the apertured plate.
