Our polyurethane fan blade for spiral classifiers is developed to deliver reliable performance in high-abrasion sand washing environments. The premium PU material ensures excellent resistance to wear and impact, significantly extending service life compared to traditional metal blades. Its flexible structure absorbs shock during operation, reducing stress on equipment and preventing damage. The blade is designed to optimize slurry movement, improving classification efficiency and reducing fine sand loss. With a lightweight structure, it allows for quick installation and easy replacement, helping reduce maintenance time and improve plant productivity.
