The combination of twin screw thread elements in a co-rotating parallel twin-screw extruder can vary based on the desired functionality and material processing requirements. Here are some basic knowledge points about twin screw thread element combinations:
CONVEYING ELEMENTS: Conveying elements are screw elements responsible for material transport, including liquid materials. The screw groove shape can be rectangular or a specially designed engaging threaded element based on relative motion principles. Conveying elements can be categorized as forward conveying or reverse conveying, and they can have single-end, double-end, or triple-end thread configurations.
SINGLE-START THREADED ELEMENTS: Single-start screw elements have high-efficiency solid conveying capability and are commonly used in the feeding section. They help improve extrusion capacity when limited by feeding rates and are suitable for conveying materials with poor fluidity, such as low-density or fine particles. Single-start threads are effective in reaction processing and offer higher output capacity, torque, and mixing characteristics compared to multi-start threads.
DOUBLE-START THREAD VS. TRIPLE-START THREAD: Double-start thread elements have a larger lead and deeper grooves compared to triple-start thread elements under the same central moment. This results in a lower shear rate, making them suitable for processing powder materials, especially those sensitive to shear, such as low bulk powder and glass fiber. Double-start threads allow for higher screw speeds, increasing production capacity. On the other hand, triple-start screw elements generate higher average shear rates and shear forces due to shallower grooves, facilitating better thermal conductivity and plasticization. However, the strong shear may not be suitable for shear-sensitive materials like glass fiber and PVC.
LEAD VARIATION AND FEATURES: The lead variation of a threaded element affects its characteristics. In a production-oriented scenario, using a thread with a larger lead can increase production rates. For extrusion of heat-sensitive polymers, a larger lead reduces material residence time, minimizing thermal degradation.
These are general principles and considerations for twin screw thread element combinations. The specific choice of elements will depend on the extrusion process requirements, material properties, and desired outcomes.
