The parallel twin screw barrel plays a vital role in twin-screw extruder systems. It comprises two parallel screws that rotate within a specialized barrel. These barrels are carefully designed to complement the screws, enabling a variety of material processing functions.
The screws within the barrel can rotate in a co-rotating or counter-rotating fashion. Co-rotating configurations are more typical in applications such as plastic compounding and extrusion. The barrel itself is often divided into segments, allowing for convenient replacement and customization to suit diverse processing needs.
Screw diameters can vary significantly, ranging from as small as 12 mm for smaller laboratory-scale extruders to exceeding 350 mm for larger industrial purposes.
Parallel twin screw barrels are widely used for compounding different types of plastics. This includes blending polymers with additives like antioxidants, UV stabilizers, and flame retardants to enhance the properties of the final plastic product. They are also used for creating polymer alloys, such as blending polycarbonate (PC) with acrylonitrile-butadiene-styrene (ABS) to combine the best properties of both materials.
As mentioned earlier, they play a crucial role in manufacturing masterbatches. By precisely mixing a small amount of highly concentrated colorants or additives with a base polymer, masterbatches are produced, which are then used to color or modify the properties of larger volumes of plastic during the final manufacturing process.
In plastic recycling facilities, parallel twin screw extruders with suitable barrel designs are used to process recycled plastics. The extruder can melt, clean, and compound the recycled plastic materials, removing impurities and re-compounding them into usable plastic pellets for further manufacturing.
