所属分类: Mixed component

SME elements are hybrid mixing elements that feature several shallow reverse reflux grooves machined into conventional forward-conveying elements. They are typically used in conjunction with resistance elements; during material conveyance, the shallow grooves on the screw flights induce melt backflow, thereby enhancing distribution performance. Selection principle: These elements are generally employed in the melt zone of twin-screw extruders.

SME Technical Details

Model: Φ18 mm ~ Φ400 mm

Material: WR5 / WR7 / WR13 / Nickel-based alloy

Performance: Wear-resistant and corrosion-resistant

WR5: The carbides in WR5 are predominantly fine, uniformly dispersed spherical vanadium carbides, with a suitable amount of chromium carbide as a secondary phase. This microstructure delivers excellent wear resistance, superior impact performance, and outstanding spalling resistance, resulting in a service life approximately three times that of 6542 material.

WR7: The carbides in WR7 are predominantly fine, uniformly dispersed spherical vanadium and chromium carbides, with a high carbide content that delivers the best overall wear and corrosion resistance, making it a high-end replacement for WR5.

WR13: Combines wear resistance and corrosion resistance, making it suitable for the battery slurry industry.

Nickel-based alloys: exhibit excellent wear and corrosion resistance.
