30 45 60 Degree Standard Kneading Block Screw Element for Extruders
Product Description:
Our Standard Kneading Block is made from high-quality aluminum
bronze surface material, known for its superior strength and
resistance to wear and corrosion. With a hardness rating of HRC
58-62, this product is built to withstand extreme pressures and
temperatures, ensuring long-lasting performance even in the most
demanding environments.
Our Standard Kneading Block is treated with a combination of
polishing and sand blasting, resulting in a smooth and even surface
that reduces friction and improves mixing efficiency. With its 30°
Kneading Block design, this product is optimized for high-capacity
mixing, helping you achieve maximum throughput and consistent
quality in your production processes.

FAQ
Q: What materials are these kneading blocks made of?
A: Our kneading blocks are made of high-quality wear-resistant alloy
steelsor stainless steels, depending on the application
requirements.
Q: What do the angles 30°, 45°, and 60° represent?
A: These angles refer to the staggered arrangement of the kneading
blocks, which influences the shearing and mixing intensity of the
material inside the extruder.
Q: How do I choose the right kneading block angle for my application?
- 30°: Gentle kneading for low shear processing
- 45°: Balanced shear and mixing
- 60°: High shear for intensive mixing and compounding
