| 摘要 |
An embodiment of the invention is a twin-screw device for an extruder system that includes a first shaft, a second shaft, a first intake element coupled to the first shaft and including a first flight, and a second intake element coupled to the second shaft adjacent the first intake element and including a second flight. The first flight and the second flight are adapted to cooperatively act as a positive displacement pump to convey material when the first intake element and the second intake element are rotated in the same direction. This action, which is a function of the rotational speed of the intake elements, transforms the use of the extruder system from "feed limited" to "torque limited". |
