High Output Low Shear SME 60/60 R Twin Screw Mixing Element For Plastic Compounding

High Output Low Shear SME 60/60 R Twin Screw Mixing Element for Plastic Compounding

SME 60/60 R is a large-lead forward slotted mixing element specially designed for 60-series co-rotating twin screw extruders. It adopts a standard 60mm lead and 60mm effective length, featuring optimized slotted thread structure based on high-efficiency forward conveying design. Different from conventional small-pitch mixing blocks, its large lead structure delivers ultra-fast melt forwarding speed to support mass continuous extrusion.

Meanwhile, the precision shallow slot layout creates mild and controllable melt backflow without generating strong shear force. Therefore, this element perfectly integrates high-yield conveying and low-shear distributive mixing. It evenly splits and reorganizes melt streams to disperse pigments, additives and low-to-medium fillers thoroughly. Besides, it produces minimal shear heat and avoids polymer thermal degradation, making it a core component for high-efficiency and high-stability compounding production of heat-sensitive materials.

• Large Pitch High-output Design: 60mm super large lead greatly improves axial melt conveying efficiency. It significantly boosts extrusion throughput and fully meets industrial mass production requirements.
• Pure Low-shear Distributive Mixing: Adopts shallow slotted backflow structure with ultra-mild mixing force. It generates negligible shear heat, effectively protecting heat-sensitive polymer chains and preventing yellowing and material degradation.
• Uniform Melt Homogenization: Evenly distributed slots continuously split, stretch and recombine melt layers. It eliminates additive agglomeration, pigment spots and flow dead zones for consistent finished product uniformity.
• Dual Performance Balance: It retains efficient forward conveying capacity while achieving fine distributive mixing. It avoids the output loss of traditional mixing blocks and the insufficient mixing defect of pure conveying blocks.
• Stable Extrusion Operation: Optimized slot structure balances melt pressure and flow velocity. It reduces extrusion fluctuation and ensures long-term stable continuous production.
• Low Residue & Easy Maintenance: Mirror-polished thread and slot surfaces reduce material adhesion. It shortens purging time and improves efficiency during frequent color and formula switching.
• Strong Process Adaptability: Multiple material options adapt to ordinary, high-wear and food-grade working conditions. Universal spline design supports flexible screw layout combination.

This large-lead low-shear mixing element focuses on high-yield and heat-sensitive material compounding. It widely applies to mass production of color masterbatch, high-speed blending of biodegradable plastics, modification of TPE/TPU soft elastomers, low and medium filler plastic compounding, food-grade plastic extrusion and all low-shear required continuous extrusion processes.
