Granulator Knife 5553 (46 x 22 x 4/3) – M35 HSS‑Co for BKG machines

Granulator Knife 5553 – a wear-resistant shredding and granulating blade engineered for BKG recycling and pelletising systems, manufactured from M35 high-speed steel with cobalt for demanding industrial use.

• M35 HSS‑Co for extended wear resistance
• Precise 46 x 22 x 4/3 profile for BKG machines
• Optimised for uniform pellet quality

Increased uptime through durable cutting geometry

The blade’s construction in M35 HSS‑Co combines hardness with hot-hardness retention, delivering reliable edge life under continuous operation. The hardened alloy resists abrasive wear and thermal softening during high-speed cutting, which reduces the frequency of replacements and contributes to predictable maintenance cycles. By using a precisely ground profile the component maintains cutting geometry longer, translating into stable throughput and fewer production interruptions for recycling and granulating processes.

Consistent output and improved material quality

Designed for shredders and granulators, this granulator knife produces a uniform particle size from varied feedstocks such as regrind, films, pipes, sprues and sheets, as described in the product context. A consistent cut reduces fines and dust generation and supports downstream processes like extrusion and pelletising with smoother melt behaviour. The defined 46 x 22 x 4/3 dimensions ensure correct fit and alignment in BKG machine housings, helping to maintain hydraulic and mechanical balance and improving overall plant efficiency.

Maintenance simplicity and process benefits

The knife’s geometry and material selection simplify regrinding and refurbishment without sacrificing fit accuracy. Precision manufacturing reduces runout and vibration, which in turn lowers bearing load and energy consumption during operation. Where process stability and repeatable pellet quality are priorities, the combination of sharp edge retention and dimensional consistency delivers measurable gains in yield and product homogeneity. The blade is intended as a production-ready wear part optimised for continuous industrial use.

With our MetavCUT brand, an economical alternative to original manufacturer parts is offered: process-optimised wear parts are precisely fitting, durable and developed specifically for productive use.

FAQ

What machines is this knife compatible with?
This knife is specified for use in BKG recycling, shredding and pelletising machines and is manufactured to the dimensions used in those systems.

What material is the blade made from and why does it matter?
The blade is made from M35 high-speed steel with cobalt, a grade chosen for its hardness and hot-hardness stability, which improves wear resistance during continuous cutting.

How does the 46 x 22 x 4/3 profile affect performance?
The defined profile ensures accurate seating and consistent cutting geometry in the machine rotor, promoting even particle size and reduced vibration.

Can this blade handle different plastic feedstocks?
Yes; the blade is designed for a range of plastics and common waste forms such as films, pipes and sprues, producing uniform granulate suitable for reprocessing.

Is the knife suitable for refurbishment?
The knife’s material and geometry allow for regrinding and reprofiling, extending in-service life while maintaining fit and cutting performance.
