How To Clean The Screw Of The Extruder?1

Screw is the core of the twin screw extruder, is also its key components, its safe and stable production, as well as its service life, will determine the production efficiency of granulation machinery and equipment, plasticizing quality, dispersion degree, melt temperature, power consumption and so on.

The following COLOWE will introduce the screw cleaning steps of the twin screw extruder:

1. First choose the correct heating device

A very common and effective method for plastic processing devices is to remove the plastic fixed on the screw of the twin-screw extruder by burning or baking. But remember here! Do not clean the screw with acetylene flame.

And in the highly developed commodity economy now, there is no shortage of a variety of screw cleaning machines (screw cleaning machines), but most of their prices are more expensive, and the effect after their use is not the same. Here is the need to use commercial cleaning machine, but also according to different manufacturers and production conditions to make decisions; Plastic modification processing enterprises can use different resins to manufacture screw cleaning machines according to their actual production conditions, which can save a lot of costs for their own units.

The first few are done correctly, but if the method is not chosen correctly, the rear effect is also greatly discounted. The first step to clean the screw is to close the feed plate, that is, close the feed port at the bottom of its hopper, and then reduce the screw speed to 15-25r/ min, here to the front of the die that melt flow stops flowing. Then note that the temperature in the cylinder heating zone should also be set in the 200°C range!
