Industrial Blades for Every Recycling Machine
Shredder blades, granulator knives, crusher blades and rotor knives — engineered from D2, SKD-11 and tungsten carbide for plastic, metal, tire and e-waste recycling lines.
The Cutting Edge of Every Recycling Line
Blades are the single most consumable component in any plastic, metal or tire recycling plant — and the single biggest driver of throughput, particle uniformity and energy cost. A dull or mismatched blade forces the motor to work harder, produces irregular regrind, and can shorten screen and bearing life. Energycle supplies precision-ground replacement blades and rotor knives for shredders, granulators, crushers, pelletizers and pulverizers, with materials matched to the feedstock — from standard D2 tool steel for film and soft plastics to tungsten carbide for aluminum, copper, tires and glass-filled composites. Every blade is heat-treated to HRC 58–62, ground to ±0.02 mm flatness, and ships with the mounting hole pattern, bevel angle and edge geometry of the OEM part you’re replacing.
Which Blade Material Fits Your Feed?
Material choice drives edge life far more than geometry. Use this table to match steel grade to feedstock.
| 재료 | 경도 | 가장 적합한 | Relative Edge Life | 비용 |
|---|---|---|---|---|
| D2 공구강 | HRC 58–60 | Film, soft plastics, paper | 1.0× (baseline) | $ |
| SKD-11 (Cr12MoV) | HRC 58–62 | Rigid PP/PE, PET bottles, HDPE drums | 1.3–1.6× | $$ |
| DC53 | HRC 60–62 | Thick-wall plastic, shock-sensitive cuts | 1.5–1.8× | $$ |
| CPM-10V | HRC 60–62 | Abrasive plastic, fiber-reinforced parts | 2–3× | $$$ |
| Tungsten Carbide Tip | HRA 89–92 | Aluminum, copper, tires, glass-filled | 3–5× | $$$$ |
How to Choose the Right Replacement Blade
1. Identify the machine type
Single-shaft shredder, twin-shaft shredder, granulator, crusher, or pelletizer — each uses a different blade family. Match the mounting pattern first, then the edge geometry.
2. Measure the feedstock
Soft plastic film tolerates D2. Rigid PET, HDPE and PP call for SKD-11 or DC53. Anything with aluminum contamination, fiberglass or mineral fill needs carbide tips.
3. Match the geometry
Hex vs. square for shredders; flat vs. angled for granulator rotors. Bevel angle (usually 30°–45°) determines cutting force and regrind particle size.
4. Plan a sharpening cycle
Carbide blades resist wear but cannot be field-sharpened. Tool-steel blades can be resharpened 6–10 times with an automatic grinder — often cheaper than buying new.
Where Our Blades Run Every Day
Engineered to process a wide range of recycling streams — from post-consumer films to rigid industrial scrap.
Make Every Blade Last Longer
Inspect knife clearance weekly
Rotor-to-bed knife gap should stay within 0.15–0.30 mm. Oversized gap wastes energy and tears instead of cutting.
Rotate blade sets
Most shredder blades have 2–4 usable edges. Rotating at scheduled intervals doubles or triples service life before re-grinding.
Remove metal contamination
Install a magnetic separator upstream. A single stray bolt can chip 6–8 carbide tips in one rotation.
Sharpen, don’t replace
안 자동 칼날 분쇄기 removes 0.05–0.1 mm per pass, giving you 6–10 re-sharpens per blade set at a fraction of replacement cost.
Four Blade Families, One Source
Match the blade to the machine. Check materials, sizes and precision options.
플라스틱 분쇄기 블레이드
Hex, square and hook knives for single-shaft and double-shaft shredders. D2 and SKD-11 tool steel, bolt-on replacement for most OEMs.
granulator blades
Rotor and stationary (bed) knives for regrind granulators. SKD-11 steel, HRC 58–62, custom lengths for any rotor diameter.
Tungsten Carbide Rotor Knives
Carbide-tipped rotor knives for abrasive feed — aluminum, copper, tires, glass-filled plastic. 3–5× longer edge life than D2.
자동 칼날 분쇄기
Resharpen your existing blades to ≤0.03 mm precision. ERM-1600 (up to 1,600 mm) and Compact (up to 1,000 mm) models.

No. D2 tool steel dulls within hours on aluminum or copper scrap. Use tungsten-carbide-tipped rotor knives for any metal-bearing feedstock.
Shredder blades deliver coarse size reduction (20–100 mm output) at slow rpm with high torque. Granulator blades run at 400–800 rpm and produce fine regrind (4–12 mm).
