Conveying Screw Elements

Two-fighted Screw Elements

Two-fighted conveying screw elements, under the conditions of Do/Di ranging from 1.55 to 1.8, achieve the optimal balance between free volume and high torque bearing capacity, thus dominating in the co-rotating twin screw compounding extruders. The Two-fighted conveying screw elements with long-pitch are prevalently utilized in the screw feeding zone and the venting zone, where the material is typically partially filled. Short-pitch screw elements are mainly employed for pressurization or to space kneading blocks to increase residence time and facilitate material melting.

Product Details

Two-fighted Screw 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
