BC55 High Shear Twin Screw Extruder Mixing Element 55mm HRC 58–64

BC55 High Shear Kneading Block | Twin Screw Extruder Mixing Element

The BC55 High Shear Kneading Block is a key mixing component for 55mm co-rotating twin screw extruders. It features a multi-lobe offset structure, and it mainly provides high shear force for material kneading and dispersion in extrusion production.

Besides, this kneading block generates stable and strong shear friction inside the barrel. It effectively disperses filler and pigment agglomerations. It mixes resin and various functional additives evenly, so it greatly improves material uniformity and finished product quality.

Moreover, its optimized offset angle balances shear strength and material fluidity. It prevents material over-shearing, burning and degradation to ensure stable long-term extrusion. Also, it works well with conveying and reverse screw elements to build an efficient screw assembly system.

Furthermore, every BC55 kneading block adopts precise CNC integrated machining. It delivers tight tolerance and smooth self-wiping surface for direct installation and replacement with no equipment changes. Multiple alloy materials and surface treatments fit high-temperature, abrasive and corrosive working conditions. If you struggle with uneven mixing or poor dispersion effect, contact our team now. We provide free screw layout optimization suggestions to upgrade your extrusion quality.

If you need parameter matching for your specific material formula, send us your production requirements. We recommend the most suitable material grade and structure solution for your working conditions.

• Powerful high shear mixing performance
