About Our Replacement Granulator & Crusher Blades
ShengAo precision-engineered replacement blades are the definitive solution for maintaining peak performance in Herbold, Zerma, Weima, and Cumberland granulators and shredders. As the core cutting edge of your recycling machinery, these blades are meticulously crafted to not only match but often exceed OEM specifications in durability and cutting efficiency. They are designed for the rigorous demands of reducing materials for recycling, disposal, or further processing, ensuring your operation runs smoothly with minimal downtime.
Unmatched Quality Assurance: Every ShengAo blade is backed by a comprehensive 1.5-year warranty, an industry-leading commitment that underscores our confidence in product longevity. We further ensure transparency and reliability through mandatory machinery test reports and video outgoing-inspection for every order.
Premium Material & Construction
We utilize a selection of premium steels to deliver optimal performance for specific applications. Our standard offerings include High-Speed Steel (HSS) and Alloy Tool Steel, both known for their superior wear resistance and toughness. We achieve a precise and consistent hardness of 58-60 HRC through controlled heat treatment processes, striking the perfect balance between edge retention and resistance to chipping.
Material & Finish Excellence: High-Speed Steel (HSS) Alloy Tool Steel Fully Customized Steel
Each blade undergoes precision grinding to achieve an exceptional surface finish of Ra 0.4 or less and a critical flatness of 0.01 or less. This meticulous manufacturing ensures a razor-sharp, burr-free cutting edge, minimizes friction, reduces heat buildup, and guarantees consistent, high-quality output from your granulator or crusher.
Key Features & Benefits
ShengAo blades are engineered to deliver tangible operational advantages and a rapid return on investment by maximizing uptime and output quality.
Extended Service Life
High toughness and wear resistance directly translate to longer intervals between blade changes, drastically reducing maintenance costs and machine downtime.
Superior Cutting Performance
The precise hardness (58-60 HRC) and fine surface finish ensure clean, efficient cuts with lower energy consumption and higher throughput.
Perfect Compatibility & Fit
Engineered to precise tolerances for seamless installation in Herbold, Zerma, Weima, Cumberland, and other major granulator models, ensuring balanced operation.
Comprehensive Support
Backed by a 1.5-year warranty, video technical support, and online after-sales service, providing peace of mind long after purchase.
Application Industries & Materials
These versatile replacement blades are built to handle a diverse range of challenging materials across multiple recycling sectors, making them a universal solution for size reduction.
