Conical twin-screw installation
Conical double screw to install bite together of the conical twin-screw see below. The installation of conical twin-screws and parallel twin-screws is not quite the same. Since the conical twin-screw has a taper, it can only be installed from the back of the screw barrel. First, remove the special tool for the screw barrel. Then, correctly engage the conical twin-screw and place it into the screw barrel. Connect it to the output shaft on the gearbox according to the position on the coupling, and then lock the screw barrel. It is ideal to control the gap of the conical twin-screw within 0.2mm, just like that of the parallel twin-screw. The gap between the conical twin-screw and the barrel is adjustable and can be appropriately adjusted according to the plasticization condition of the material. Due to the differences in design concepts among various extruder manufacturers, the specific gaps should refer to the instruction manual of the extruder.
