A parallel twin screw barrel plays a pivotal role in the operation of twin-screw extruder systems. It comprises two parallel screws that rotate within a specially designed barrel.
These barrels are meticulously crafted to complement the screws, enabling a seamless execution of various material processing tasks. The screws can either rotate in the same direction (co-rotating) or in opposite directions (counter-rotating).
Co-rotating configurations are commonly preferred for applications such as plastic compounding and extrusion. The barrel is often segmented to allow for convenient replacement and customization to accommodate diverse processing needs.
The diameter of the screws can vary significantly, ranging from as small as 12 mm in laboratory-scale extruders to exceeding 350 mm for extensive industrial purposes.
Parallel twin screw barrels are extensively employed in plastic compounding for blending various types of plastics. This process involves mixing polymers with additives such as antioxidants, UV stabilizers, and flame retardants to improve the characteristics of the resulting plastic product. Additionally, these barrels are utilized for creating polymer alloys, like blending polycarbonate (PC) with acrylonitrile-butadiene-styrene (ABS) to combine the desirable properties of both materials.
Parallel twin screw barrels also play a vital role in the production of masterbatches. By accurately blending a small quantity of highly concentrated colorants or additives with a base polymer, masterbatches are manufactured. These masterbatches are later used to color or modify the properties of larger quantities of plastic during the final manufacturing phase.
In plastic recycling facilities, parallel twin screw extruders with appropriate barrel designs are used to process recycled plastics. These extruders can melt, clean, and compound the recycled plastic materials, eliminating impurities and re-compounding them into usable plastic pellets for further manufacturing.
