The difference between parallel and conical twin screw extruderThe difference between parallel and cone bai twin screw extruder
1. Diameter: The diameter of the parallel twin screw is the same, and the diameter of the small straight end of the conical twin screw is different from the diameter of the big end.
2. Concentric distance: the center distance of the flat twin screw is the same, the two axes of the conical twin screw are at an angle, and the size of the center distance changes along the axis.
3. L/D ratio: Parallel double screw (L/D) refers to the ratio of the effective part length of the screw to the outer circle of the screw, and conical double screw (L/D) refers to the effective part length of the screw and the diameter and small end of the large end Ratio of average values of end diameters
