SME Screw Element
Product Name: SME (Screw Mixing Element)
Model：φ11 mm ~φ350mm
Applicable Brands：Most well-known extruders on the market
Material: Tool steel, HIP, stainless steel, nickel-based alloy, cobalt-based alloy, etc.
Properties:Wear-resisting, Corrode-resisting and Durable
Structural Features:
The SME element is essentially a standard conveying screw with strategically placed slots or grooves along the flight edges, designed to enable partial material leakage. It retains forward conveying capability while introducing axial distributive mixing as a key advantage.
The SME unit is a hybrid mixing element featuring several shallow reverse-flow channels integrated into a conventional forward-conveying screw design. These channels, typically oriented opposite to the main conveying direction, create multiple reflux paths along the screw flights.
Functional Characteristics:
Forward Conveying with Enhanced Mixing: Maintains primary material transport while inducing axial redistribution through the reflux channels, improving both distributive and dispersive mixing.
Low Shear Heat Generation: The design minimizes intense shear zones, resulting in significantly lower heat generation compared to other mixing elements (e.g., kneading blocks).
Energy Efficiency: Among screw mixing elements, the SME exhibits the lowest energy consumption due to its gentle mixing action, making it ideal for heat-sensitive materials.
Applications:
Melting and Metering Zones: Commonly placed in the melting and extrusion sections of twin-screw extruders to enhance melt uniformity without excessive shear.
Intermediate Mixing in Low-Shear Configurations: Positioned between 45° or 60° kneading blocks in low-shear screw profiles to provide supplementary distributive mixing, ensuring consistent dispersion of additives or fillers.
Heat-Sensitive Processes: Suitable for processing polymers prone to thermal degradation (e.g., PVC, certain engineering plastics) by maintaining low shear stress while improving mixing efficiency.
The SME element’s unique combination of conveying efficiency and mild mixing action makes it a versatile choice for applications requiring uniform dispersion with minimal thermal or mechanical stress on the material.
