What is the importance of parallel twin screw barrels

A Parallel twin screw barrel is critical for the quality of a screw. This means that there must be sufficient clearance between the screw and the barrel. The parallel twin screws are also critical for the accuracy of a screw. If the screws are not parallel to the barrel, a leaking screw will occur. Moreover, a parallel twin screw barrel should be free of any voids.If you're looking for a barrel that has more than one screw, consider purchasing a Parallel Twin Screw barrel. These barrels are made with two intermeshing screws and can be used in a variety of industries.

From boilers and heat exchangers to metal processing and mining, power plants, and nuclear facilities, these screw barrels can perform the job you need done. They're also widely used in general industrial and aerospace applications.These screw barrels are available in a variety of diameters. The largest model is capable of producing up to 2275 kg/hr of rigid PVC pipe and profile. A bimetallic coating is used on both the screw and barrel to provide excellent wear resistance and a long service life. They are manufactured from high-quality raw materials, ensuring maximum performance and reliability.The screw and barrel are designed with a modular building block design to make changes and combinations possible to maximize their performance.

This enables a good mix and self-cleaning effect for both materials. They are also designed to avoid the extrusion of material into the screw and barrel wall. The rotating material constantly updates the surface of the barrel, making them ideal for deodorization and dissolving volatile materials at high speeds.The main differences between parallel and conical twin screws are in the diameter of the screw and the length of the effective part. In a parallel twin screw, the outer diameter of the screw is the same. In contrast, a conical twin screw has two diameters with the same effective part length.

The geometrical differences between these two screw types are significant and lead to differences in performance and structure. They are used primarily in a range of applications.Despite the differences in diameter, parallel twin screw extruders have the edge over conical twin screw barrels. They increase the aspect ratio and increase the application range of the product. This makes parallel twin screw extruders a superior choice in many industries. A large axial thrust is created by the melt in the parallel twin screw extruder, which generates a high pressure at the head of the screw. The bearings must be able to withstand this high pressure.
