Some of the features of twin-screw extruder

Dec 12, 2017

1 wear condition

Because of the convenience of opening, it can be found at any time to find the degree of wear and tear of the bushing of the screw element and the inner sleeve of the cylinder, so that it can be effectively repaired or replaced. Not to find out when the product is out of problem, causing unnecessary waste.

2 reduce production cost

When making masterbatch, it often needs to change color. If necessary, replace the product, open the processing area in a few minutes, and observe the mixing process by observing the melt profile on the whole screw. At present, when the ordinary twin screw extruder is changing the color, it needs a lot of cleaning machine to make the machine, not only time consuming, electricity, but also the raw material. The split twin screw extruder can solve this problem. Only a few minutes after changing colors, the machine can be opened quickly and manually cleaned, so that no cost or less cleaning material can be used, and the cost is saved.

3 improve labor efficiency

In the maintenance of the equipment, the ordinary twin screw extruder often has to remove the heating and cooling system first, and then draw the screw out of the whole. The split double screw is not used. As long as several bolts are loosened, the worm gear box handle device is lifted, and the upper part of the machine barrel is lifted, and the whole cylinder is opened, and then the maintenance is carried out. This not only shortens the maintenance time, but also reduces the labor intensity.

4 high torque and high speed

At present, the development trend of twin-screw extruders in the world is developing towards high torque, high speed and low energy consumption. The effect of high speed is high productivity. The split twin screw extruder belongs to this category, and its speed can be up to 500 rpm. It has unique advantages in the processing of high viscosity and heat sensitive material aspects.

At high speed, the core technology of high torque, high torque gear box asymmetrical and symmetrical currently only Germany and Japan related manufacturers to master the core technology, the highest speed can reach to more than 1800, while domestic master the core technology, only Sichuan is a science and technology, one of the main choice is currently the domestic high-end materials processing manufacturers, belonging to the domestic independent innovation projects encouraged by the state

5 wide range of applications

It has a wide range of applications and can be applied to the processing of a variety of materials

6 high yield and high quality

With the other advantages of the common twin screw extruder, high output, high quality and high efficiency can be achieved.
