Conical Double Screw For Extruder , Plasticized Conical Double Screw​

Introduction to Conical Twin Screw
1. Conical twin-screw is different from parallel twin-screw in appearance. Its two ends have different diameters. The diameter of the feeding section is large, while the diameter of the homogenization section is small, and the middle is gradually transitioned. The conical twin-screw is a meshing type, most of which are counter-rotating. Two conical screws mesh with each other in the barrel and rotate in opposite directions, and there is a reasonable gap between the top of the spiral edge of one screw and the root of the other screw. Due to the counter-rotation, the spiral path of the material on one screw is blocked by the other screw, and the material can only move axially through the gaps in each part under the push of the screw.
2. When the material passes through the radial gap between the two screws, it is like passing through the nip of two rollers. The stirring and shearing are very intense. Therefore, the plasticization of the material is very uniform, which is especially suitable for processing PVC plastics.
3. GWELL company uses high-precision machine tools to process the screw, so that the processed screw has higher precision.
