Plastic Scrap Grinder Blade

Plastic scrap grinder blades, essential for size reduction in recycling, are precision-engineered cutting tools typically made from high-strength alloy steels like D2, SKD-11, HSS, or 6CrW2Si, ensuring high hardness, exceptional wear resistance, and strong impact toughness for long service life. Designed as rotating or fixed knives (e.g., flat, claw, or granulator-style) for crushers and granulators, these blades are heat-treated to achieve optimal hardness and edge retention, effectively shearing and grinding diverse plastic materials, such as HDPE, PP, and film, into uniform granules for subsequent reprocessing. Their design, including serrated edges or V-shaped geometry, is crucial for efficiency, low energy consumption, and high throughput across various plastic scrap types.
