With the advancement of science and technology, an increasing number of people are focusing on the input and use of industrial equipment. In fact, there are a growing number of machinery and equipment that have changed the mode of production of companies, and they have different functions and characteristics. Take for example the mixer, which mixes different forms of substances in order to produce a coating powder that meets industrial standards and is homogeneous.


The product we are introducing today is the Twin Screw extruder, a multifunctional machine that mixes, crushes, shears, presses, and forms substances. This article will explain how to properly operate and maintain a Twin Screw Extruder.

The working principle of a Twin Screw Extruder.


A Twin Screw extruder is a machine consisting of two identical screws mounted on shafts and rotating in the same direction within a fixed closed housing called a 'barrel'. By continuous rotation, the machine can extrude the corresponding product. It is important to note that the extruded product may be a plastic compound or a chemically modified polymer. This shows that Twin Screw extruders have a wide range of applications.



How to operate a Twin Screw Extruder?


·Pre-use inspection

Before using the Twin Screw extruder. Make sure you carry out a thorough inspection of the components and check the tightness of all screws to prevent accidents. In addition to this, it is also necessary to check the components regularly.


·Unforeseen circumstances

In the event of a sudden power failure during production, it is important not to panic and to wait slowly for the power to be supplied. When the power supply is restored, the barrel sections must be reheated to the required temperature and held for a period of time before the extruder can be started.


·Operating steps

The first thing to do is to close the main switch. Afterward turn on the power supply at the operating panel. Next. Start the machine according to the set temperature for each temperature zone. Add cooling water to the cooling tank. In addition to this, the vacuum pump can be started when the operation needs to be switched on.


These are the specific operating steps and precautions for Twin Screw extruders. Our Twin Screw extruders are equipped with a comprehensive safety protection system, which also ensures the safety of the user. However, the above points still need to be considered.


How to maintain a Twin Screw Extruder?


Although the Twin Screw extruder has a long service life, when the Twin Screw extruder is used for more than 500 hours, there will be iron filings or other impurities in the gearbox from the gear grinding down. At this time we need to clean the gears and add a certain amount of lubricant as appropriate. This is not only to ensure the efficiency of the Twin Screw extruder but also to extend the service life of the product.


In conclusion, while the structure and operation of Twin Screw extruders are simple, it is important that we regularly check and maintain them. Otherwise, we cannot guarantee whether the Twin Screw extruder can be used properly. It is important to note that the split Twin Screw extruder can be opened by loosening a few bolts and turning the handle unit to lift the upper part of the barrel, which makes it very easy to maintain.
