How to use a Twin Screw Extruder effectively?

As common extruder equipment, single screw extruder is used in the plastic processing industry with low noise, smooth running, high load capacity and long life. However, single-screw extruder is not the product we are going to introduce, our main character today is Twin Screw Extruder, which is a kind of equipment developed based on single-screw extruder.

This article will take an overview of the operating principles and considerations for the use of Twin Screw Extruders. At the same time, the principles that need to be followed for the work of Twin Screw Extruders will be specifically mentioned.

The main function of a Twin Screw Extruder.

Twin Screw Extruder is a kind of machinery and equipment commonly used in industrial processing, which is developed based on single-screw extruder. It has been widely used in many fields of applications because of its features such as high feeding performance, mixing and plasticizing performance, and exhaust performance.

The parts of Twin Screw Extruder are comparable to single-screw extruder, but there are still many differences between it and single-screw extruder, such as the function. The main functions of a Twin Screw Extruder are heating, mixing, blending, crushing, shearing, and pressing. It can produce a high-quality coating powder by precise control of processing conditions.

How to maintain a Twin Screw Extruder.

For any machine or equipment, regular maintenance is very important, and Twin Screw Extruders also need regular maintenance. After a period of usage, it is necessary to carry out a thorough inspection of the extruder's components and check the tightness of all screws. In addition, we need to check the wear of the moving components, add lubricant regularly, clean the gears, and change the lubricant of the gearbox.

Principles to follow when using Twin Screw Extruders.

There are three main principles that need to be followed when using a Twin Screw Extruder, namely the structural principle, the temperature principle, and the deceleration principle, which will be the emphasis of this section.

·Structural principles

The Twin Screw Extruder is composed of the main drive, charging device, barrel, and screw. Its structure is not complicated and is frankly a screw turning in the barrel and pushing the plastic forward. We need to pay attention to overcome the friction and the adhesion of the melt on the barrel wall, which is the resistance that may affect the performance of the equipment.

·Speed reduction principle

In most extruders, the change of screw speed is achieved by adjusting the motor speed. If the deceleration rate is wrongly matched with the work, too much energy will become wasted, thus affecting the efficiency of the Twin Screw Extruder. The Twin Screw Extruder will generate too much frictional heat when it engages in speed rotation, which needs attention.

Finally, it is important to follow the temperature principle because extrudable plastics are thermoplastics, and they will solidify again when they cool down. Therefore, heat is needed during the extrusion process to ensure that the plastic can reach the melting temperature. These are all the considerations and principles of Twin Screw Extruders.
