ZE60 ZE75 Medium Shear Kneading Block | Co-Rotating Twin Screw Extruder Spare Parts
ZE60 / ZE75 Medium Shear Kneading Block adopts standard 45° staggered kneading disc design, the universal mixing element for ZE series co-rotating twin screw extruder. This medium shear kneading block balances dispersive mixing and distributive mixing perfectly. It provides moderate shear force and proper forward conveying capacity, avoiding excessive heat generation caused by high shear. It applies to melting zone and mixing zone. It homogenizes polymer matrix, breaks filler agglomerates, and realizes uniform blending of additives. The component follows Erdmenger intermeshing self-wiping profile. Internal spline fully matches original ZE60 and ZE75 screw shaft. Customers widely adopt this kneading block for plastic compounding, masterbatch production, recycled plastic modification and polymer alloy extrusion.
- Balanced medium shear mixing: 45° staggered structure delivers moderate shear, suitable for most general modification formulas.
- Combine dispersive & distributive mixing: Break particle agglomeration while evenly distributing all components in melt.
- Controllable residence time: Maintain proper forward conveying ability, reduce risk of thermal degradation of heat-sensitive materials.
- Excellent self-wiping performance: Intermeshing profile eliminates material dead zone, prevent carbon deposition.
- Modular assembly: Freely combine with feeding elements, conveying segments and barrier elements to build complete screw configuration.

We supply standard ZE60 and ZE75 medium shear kneading blocks and support customized length & disc combination. Standard sizes have short lead time. When sending inquiry, please confirm extruder model, screw layout drawing, processing material and filler content. All elements pass dimension tolerance inspection and hardness test before delivery.
Q1: Can these kneading blocks replace original spare parts directly? A1: Yes. Geometry, outer diameter and internal spline comply with OEM standards, direct installation without adjustment.
Q2: What is the difference between 45° medium shear, 30° low shear and 60° high shear kneading block? A2: 30° low shear owns stronger conveying capacity and mild shear; 45° medium shear balances conveying and mixing (universal type); 60° high shear brings stronger dispersion but weaker forward transport and higher melt temperature.
Q3: How to choose suitable base material? A3: Nitrided 38CrMoAlA for common plastic; WR5 / high speed steel for medium filler; SAM26 / CPM10V for high filler, glass fiber abrasive materials.
Q4: Can I customize the number of kneading discs and overall length? A4: Customization available. We develop products according to your screw arrangement drawing and provide professional screw configuration suggestions.
Q5: Production capacity and delivery time? A5: Monthly production capacity: 8,000–12,000 PCS. Standard products: 3–7 working days; customized parts:7–15 working days. 12-month warranty under normal operating conditions.
