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
