What are the advantages of twin-screw extruders?

The twin-screw extruder is developed on the basis of the single-screw extruder. The difference between the twin-screw extruder and the single-screw extruder is mainly reflected in two aspects: the material transfer method and the material flow velocity field. Compared with the single screw extruder, the complex flow spectrum of the material in the twin screw extruder shows macroscopic advantages that the single screw extruder cannot match, such as adequate mixing, good heat transfer, high melting capacity, good exhaust capacity, and good control of the material temperature. This article will briefly describe the advantages of twin-screw extruders.

Easy to observe wear and tear

Since it is easy to open, the degree of wear of threaded elements and barrel bushings can be detected at any time, so that effective repair or replacement can be carried out. No unnecessary waste due to detection of problems in extruded products only when they occur.

It helps to reduce the production cost

When manufacturing masterbatches, it is often necessary to change the color, and if it is necessary to change the product, the open processing area is opened within a few minutes’ time, and additionally, the mixing process can be analyzed by observing the melt profile on the entire screw. Ordinary twin-screw extruders require a large amount of clearing material to clear when changing colors, which is time-consuming, power-consuming, and a waste of raw material. The split twin-screw extruder can solve this problem. When changing colors, it only takes a few minutes to quickly open the barrel and clean it manually, so that no or less cleaning material can be used, saving costs.

Improves labor efficiency

During equipment maintenance, ordinary twin-screw extruders often have to remove the heating and cooling system before the screw is withdrawn as a whole. In contrast, the split twin-screw does not need to be removed, as long as a few bolts are loosened and the upper half of the barrel is lifted by turning the worm gearbox handle device to open the entire barrel for maintenance. This shortens the maintenance time and reduces the labor intensity.

High torque and high speed

The development trend of twin-screw extruders in the world is to develop in the direction of high torque, high speed, and low energy consumption, and the effect of high speed is high productivity. The split twin-screw extruder belongs to this category, and its speed can reach plus 500 rpm. Therefore, it has unique advantages in processing high viscosity and heat-sensitive materials.

Wide range of applications

A wide range of applications for a wide variety of materials

High output and quality

The twin-screw extruder has other advantages, such as high output, high quality, and high efficiency.
