Plastics and Rubber Industry Applications | Wear-Resistant Granulator Blades and Shredder Knives
Industry Challenges and Requirements
In plastic recycling processes involving PCR and PIR materials, as well as pelletizing operations, plastic waste may contain glass fibers, mineral fillers, or metallic contaminants that can cause rapid blade wear, edge chipping, and even blade breakage. As blades become dull, frictional heat can cause plastics to melt and adhere to the cutting edge, seriously affecting the size uniformity of the processed material.
Core Application Scenarios
Injection Molding Scrap and Centralized Granulation:
High-speed cutting and granulation of injection molding scrap, plastic lumps, and blow-molding scrap for regrinding and reuse.Plastic Extrusion Pelletizing:
Underwater and strand pelletizing systems process extruded plastic materials into uniformly sized pellets.Heavy Scrap and Tire Primary Shredding:
Heavy-duty dual-shaft shredding of end-of-life tires, large plastic drums, and discarded appliance housings during the initial size-reduction stage.
Recommended Blade Options
SKD-11 / D2 High-Alloy Granulator Blades:
A versatile choice for general plastic granulation, offering stable wear resistance and easy resharpening.Carbide-Tipped Granulator Blades:
Suitable for glass-filled and reinforced high-hardness plastics, providing improved wear resistance and extended service life in abrasive applications.Carbide-Tipped Granulator Blades:
CrMoV Alloy Steel Shredder Knives: Offer high toughness and impact resistance to reduce the risk of blade breakage under heavy-impact conditions.
