During long-term use, blade wear in shredders is inevitable. Severely worn blades reduce shredding performance, increase energy consumption, and may even damage the motor. Therefore, understanding blade replacement cycles is critical. In general, blades used for plastic and rubber have a longer lifespan, while those used for metal shredding wear out faster and require more frequent replacement.
To control costs, companies can adopt a “sharpening + replacement” strategy. Some blades can be restored through professional sharpening, which extends their usability. In addition, bulk purchasing and choosing cost-effective materials are also effective ways to reduce expenses. By planning blade use and replacement strategically, companies can boost production efficiency while significantly lowering operational costs.
