          Advantages of conical twin screw extruder

 For users, it is important to the choose and buy of twin screw extruder, the different types of twin screw extruder with different properties and applications, therefore, must want to understand all kinds of performance and the application of the twin screw extruder.For example, the mesh type synthetic rotating twin screw extruder for its high speed, shear rate, combination of screw, it widely applies to the thermal decomposition of the polymer modification, blending, filling, fiber reinforcement and material of reactive extrusion.For example, the mesh type differential rotating twin screw extruder, because of its good mixing plasticization functions, its biggest characteristics is a direct forming PVC powder.Such as change the geometric structure of the screw, can also be used for other materials processing, but its strength is still the PVC processing.According to the size of the section, plastic extrusion, by extrusion amount again to choose the specifications of the twin screw extruder.In the plastic processing and molding process conditions under the condition of basically the same, conical double screw extrusion mechanism to adapt to the larger head pressure, parallel twin-screw extrusion function adapted to small head pressure.

Two root conical screw horizontal arrangement, two axis in an Angle into the barrel, the center distance of two axis from the small to the big end increases gradually, make the transmission gearbox output shaft have two larger center distance, the transmission system of gear and gear shaft and bearing of the gear shaft radial and thrust bearings have larger installation space, it can device of the radial and thrust bearings of large size, the shaft is enough to meet the diameter of axle torque, so big torque, load bearing ability is an important characteristic of conical twin screw extruder.This parallel twin-screw extruder is incomparable.

Conical double screw extruder with the arrangement of two screw Angle, so the transmission gearbox output shaft have two larger center distance, in the gear box unit before and after the two staggered larger thrust self-aligning ball bearings, enough to stop by the axial force formed by the pressure of the nose, the characteristics of bearing capacity is big, the gearbox manufacturing cost is low, maintenance is convenient.
