The Heavy Source SG3000 Single-Shaft Shredder is a high-performance plastic recycling machine designed to tackle diverse materials, from tangled PE films to fiberglass-reinforced HDPE/PP pallets. With a 1,200mm alloy steel shaft, multi-row angled blades, and 18+ pre-programmed settings, it produces 20–100mm granules with 95% consistency. The machine improves washing efficiency by 40% when processing 30mm particles, while reducing energy consumption by 30% and downtime by 50%. Built for adaptability, durability, and precision, it is a key solution for effective plastic waste treatment and recycling.

Meet the Heavy Source SG3000 Single-Shaft Shredder: A Precision Machine for Plastic Recycling

Every morning at 8 AM, as sunlight spills over the factory’s steel frame, I begin my daily “chewing” work—transforming mountains of waste plastics into reusable granules. My “teeth” are multi-alloy cutting tools, my “stomach” can devour large plastic pallets, and my “heart” is a 1,200mm alloy steel main shaft that delivers “gentle disassembly” to every piece of waste plastic with each rotation.
Join me as we explore the world of plastic pre-shredding, where a machine’s “steel tenderness” battles white pollution and breathes new life into discarded materials through precision engineering.
My first task of the day involves muddy greenhouse films—tangled PE sheets that once choked traditional machines, causing costly downtime. But I’m different. My multi-row angled blade design acts like a master tailor’s scissors. As the main shaft rotates at medium-low speed, the blades slice the films from multiple angles, reducing them to <40mm granules in under 10 seconds. The fragments fall seamlessly through the bottom screen.
Next, forklifts deliver industrial pallets and pipes embedded with 30% fiberglass—bulky, hard materials that traditional equipment struggled to process without pre-cutting. With me, operators load entire pallets directly into my hopper. The intelligent arc-shaped material pressing device guides them gently into the cutting zone, where my knife sets work like piano keys. In 30 seconds, the pallets transform into uniformly sized granules.
Years of operation have honed my adaptability. Whether handling flexible films, mixed waste, or heavy-duty pipes, I switch seamlessly between 12+ pre-programmed modes to achieve 20–100mm particle sizes with 95% consistency.
Pre-shredding is the “first gateway” to plastic recycling:
- Material Variability: PET/PE/PP’s diverse hardness and toughness, plus metal/sand contaminants, often jam traditional machines.
- Optimal Particle Size:
- 30mm granules boost washing efficiency by 40% compared to 100mm (3x larger surface area for faster degreasing).
- Over-shredding (e.g., <20mm) causes 15–20% material loss during washing and increases wastewater pollution.
- Downstream Impact: Inconsistent particle sizes from hard plastics like nozzle scrap can clog extrusion screens, reducing output by 30%.
The quality of pre-shredding directly determines the success of chemical, physical, or energy recovery processes.
Heavy Source’s R&D has equipped me with cutting-edge capabilities:
- Smart Feeding: The arc-shaped pressing device ensures optimal material positioning, reducing cutting resistance by 25%.
- Durable Blades: Made from SKD-11 alloy steel (HRC 58–62), my blades outlast conventional tools by 2x, even when processing fiberglass-reinforced plastics.
- Customizable sizes (20–100mm) with ±2mm tolerance.
- 95% of output meets specified standards, ideal for chemical recycling (e.g., pyrolysis) and pelletizing.
- 18+ pre-set programs handle everything from films to automotive parts.
- Output ranges from 2–30 TPH, configurable via the intuitive HMI interface.
- Low Energy Consumption: 0.8–1.2 kWh/ton, 30% more efficient than competitors.
- Dual Safety System: Overload protection + emergency stop reduces downtime by 50%.
Conclusion
I am the Heavy Source SG3000 Single-Shaft Shredder—engineered for precision, durability, and sustainability. By addressing the critical challenges in plastic recycling, I help transform waste into value, one granule at a time.

This machine sounds like a game-changer for plastic recycling! Love the piano keys analogy for the blades.
@PincerPundit:Totally agree! The analogies really help non-engineers like me understand how this advanced tech works.
Finally some real innovation in waste management. That 95% consistency rate is impressive 👍
How often do those SKD-11 alloy blades need replacement in real-world use? The 2x durability claim seems optimistic.
The way this describes the shredder as having a “heart” and “teeth” is kinda creepy ngl 😅
30% more energy efficient than competitors? That’s what I call progress in industrial machinery!
I work at a recycling plant and we desperately need this. The amount of downtime we get from jammed machines is ridiculous.
“Steel tenderness” battling white pollution – that’s some poetic industrial writing right there
The article doesn’t mention noise levels – these things are usually crazy loud. What’s the dB on this model?
2-30 TPH with that consistency is wild. Heavy Source really stepped up their engineering game.
@LittleRedRidingHood:The engineering behind the arc-shaped pressing device seems brilliant. Small innovations can make huge differences in industrial equipment!
Anyone else imagining this shredder as a Transformers character after reading this? “Optimus Grind” or something lol
The part about how it handles fiberglass-reinforced plastics is impressive. We’ve had so many blade replacements because of that at our facility.
Wish we could see a video demo of this thing in action! The description makes it sound almost like a living creature 😄
As someone who’s worked with older shredders, that 50% downtime reduction sounds too good to be true. Anyone have real-world experience with this model?
