As a crucial component of shredders, the blades' lifespan directly impacts the machine's performance. Shredder blades come in various shapes and structures depending on the materials being shredded. Shredders are widely used for shredding wood, PE pipes, plastic bottles, waste copper wire, plastic film, woven bags, paper, circuit boards, thin metals, medical supplies, waste appliances, vehicle recycling, and municipal solid waste.
Blades can be categorized by shredder type: single-shaft shredder blades, dual-shaft shredder blades, triple-shaft shredder blades, and quadruple-shaft shredder blades. So, what are the main factors affecting the lifespan of shredder blades?
- Blade Structure: Cutting gap between blades, blade angle, surface roughness of the blade edge;
- Blade Raw Materials: Content of beneficial and harmful alloying elements;
- Blade Heat Treatment: Hardness of the blade, uniformity of hardness on the same surface;
- Blade Rotation Speed: The shredding speed of the blade relative to the material;
- Blade Shredding Force: The power of the shredder equipment.
