TME Screw Element
Product Name: TME (Turbin 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 TME (Turbin Mixing Element) stands as the earliest toothed kneading element, characterized by a circular disc adorned with numerous teeth around its circumference, resembling a gear. These teeth can be configured as either straight or helical. The element offers two installation options:
Disc Configuration: Assembled in groups with axial spacing via spacer rings.
Integrated Design: Fabricated as a single, cohesive unit.
Typically employed in sets, TME elements on twin screws are arranged alternately along the screw axis without meshing. This arrangement creates non-interlocking zones between the toothed discs, enabling material splitting as it passes through.
Functional Characteristics:
Superior Transverse Mixing: The circumferential teeth induce intensive lateral splitting and redistribution of the material flow, maximizing the specific surface area for component interaction. This design excels at distributive mixing, ensuring uniform spatial distribution of materials.
Customizable Mixing Modes: By adjusting the tooth orientation (forward, reverse, or straight), the flow path and shear intensity can be tailored to accommodate different materials, optimizing mixing efficiency for diverse applications.
Limited Conveying Capacity: Unlike conventional screw elements, TMEs lack inherent forward or reverse conveying capabilities. Material transport relies on adjacent screw sections. Additionally, the non-meshing design results in minimal self-cleaning action, which may cause slight material retention but enhances distributive mixing.
Applications:
High-Precision Distributive Mixing: Ideal for processes requiring uniform dispersion, such as pigment incorporation in color masterbatches or additive blending in plastics, reducing inconsistencies in product appearance or performance.
Multiphase System Blending: Incompatible polymer blends (e.g., PP/PS) benefit from TME’s ability to promote interfacial contact during the initial mixing stages, preparing the material for subsequent shear-intensive dispersion.
Shear-Sensitive Material Processing: The gentle mixing action makes TME suitable for shear-sensitive materials (e.g., elastomer-plastic blends), ensuring component distribution without excessive degradation.
TME’s exceptional transverse mixing efficiency makes it a preferred choice for applications prioritizing distributive mixing over dispersive shear, particularly in high-precision compounding processes.
