Kneading Screw Elements

L-kneading elements


L-kneading element is usually reversed 45° , it has a strong dispersion & distribution mixing capacity and reverse conveying capacity (pressure building capacity), which is between the reverse conveying element and 90° kneading element. It can adjust the filling rate and residence time of the material. It is often used before ventng and vacuum zone.

L-kneading elements Technical Details

Model: Φ 18 mm~Φ 400 mm

Material: WR5/WR7/WR13/Nickel based alloy

Performance: Wear resistant and corrosion-resistant

WR5: The carbide of WR5 is mainly composed of small dispersed spherical vanadium carbide, supplemented by an appropriate amount of chromium carbide. It has good wear resistance, excellent impact performance, and good anti peeling performance. Its service life is about three times that of 6542 material.

WR7: The carbides in WR7 are mainly small dispersed spherical vanadium carbide and chromium carbide, with a large number of carbides and the highest comprehensive wear and corrosion resistance, making it a high-end alternative to WR5.

WR13: It has both wear and corrosion resistance, suitable for the battery slurry industry.

Nickel based alloy: has good wear and corrosion resistance


L-kneading elements Function

Stronger shear force.

Strong distribution ability.

Good reverse conveying effect.
