This system offers increased efficiency and capacity, making it suitable for a wide range of heat-sensitive materials and high powder filling operations. Examples include PVC, XLPE, halogen-free flame retardant cable, shielding material, and carbon black master batch.
The compounding process using twin-screw technology is highly efficient. The finished material is extruded without any pressure build-up in the die head. It is then cooled and stabilized using a low-speed, low-shear single-screw process. This avoids the high shear forces of the twin-screw, which can cause high melting temperatures and decomposition of materials in the head retention area.
The twin-screw extrusion system is divided into separate parts for drying, solidifying, and compounding. The single-screw part is dedicated to the cooling and stabilization of the material. This design prioritizes the avoidance of decomposition in both parts and ensures optimal performance of the main engine.
In water ring pelletizers, the cooling and transport medium, water, does not come into contact with the die plate. The circulating knives cut the melt strands and fling the hot molten pellets into the circulating water ring. The water flow conveys the pellets out of the pelletizer hood.
Cooling Efficiency: Water ring cutting allows for rapid and efficient cooling of the extruded plastic, which is particularly important for heat-sensitive materials. The immediate cooling helps prevent degradation and maintains material properties.
Minimal Dust: The cutting process takes place within the water, minimizing the generation of dust and airborne particles, which is crucial for a clean and safe working environment.
Consistency: Water ring cutting produces uniform pellet or granule sizes, ensuring consistent material properties and performance in downstream processes.
Compact structure: It does not need a cooling water tank as used in strand line cutting process, so it is more convenient for setting up a twin screw compounding line with water ring die face cutter.
