Masterbatch Twin-Screw Granulator Cleaning Method

The twin-screw granulator cleaning color masterbatch is mainly manifested in the following aspects:

1) Mandatory transportation. Turn the twin-screw extruder in the direction of the teeth, in contrast, and an extruder screw to pull the material into the tooth slot, and another extruder screw puts the material From the gap, the material is turned from a extruder screw guide to another extruder screw tube, and the material is in a "∞" shape to the engine orientation is mandatory to transport.

2) Airflow delivery and stirring. In the same direction, the twin-screw extruder is smaller at the gear, the rib edge and the speed direction of the screw guide are opposite, and the relative speed is large, and thus the tooth region has a high segmentation rate, the shear force is large, and the mixture is mixed. The actual effect is far better than the twin-screw extruder and abnormal rotation twin screw extruder.

3) Self-cleaning. Turn the twin-screw extruder in the same direction because the gear rib and the speed direction of the screw guide are opposite, and the relative speed is large, and there is a high segmentation rate, which can be scraped off the adsorption on the extruder screw. There is a good self-cleaning effect, thereby so that the waiting time of the material is short, it is not easy to generate partially solubilization.

4) Melting of the material. The size of the extruder screw gap has a greater impact on the material melt quality. The smaller the gap, the larger the shear force, but the amount of material selected is reduced; the greater the gap, the amount of material is increased, but the shear force is reduced.

5) The shrinkage of the material. There are much more ways to scale small materials in the same direction, and the comprehensive utility is good.

6) Fertilization method. In the same direction, the twin-screw extruder requires uniformity by quantity, and the metering hunger is used.

7) Exhaust. Because it is a hungry feed, the outer thread transport element of the large pitch can be selected such that the screw groove is in a zero burden state in the unfilled state, and the exhaust segment can be set.

When the two-screw extruder produces the masterbatch, it often needs to replace the color. If necessary, open the open production area in a few minutes, and can also be observed by observing the melt section on the entire extruder screw. To analyze the stirring. At present, the ordinary twin-screw extruder is replaced with color, and it is necessary to use a lot of clearing machines to make a cleaner, while time-consuming, power consumption, and waste of raw materials. The split double-screw extruder can solve this problem. When replacing the color, only a few minutes can open the cartridge in time, perform artificial cleaning, so you don't have to use or use a cleaning material to save costs.
