Why the Right Metal Shredder Matters for Your Scrap Yard
If you are looking for a metal shredder for sale, you are probably expanding a scrap yard, foundry, or metal-processing facility in Southeast Asia. The machine you choose determines how much of your incoming scrap you can turn into clean, sellable fractions — and how reliably you can do it shift after shift. This guide walks through the selection criteria and the supplier checks that matter most for buyers in Vietnam, Indonesia, Thailand, Malaysia, and the Philippines.
Match the Shredder to Your Feedstock
Start with what you actually process. Light sheet steel, aluminum profiles, and cable call for a compact twin-shaft machine such as the TG-LightMetal 80 (2x15 kW). Machining swarf and turnings need a purpose-built unit like the TG-AluShred 120 (2x18.5 kW), whose low-speed shearing reduces work-hardening of aluminum. Mixed scrap and bulky items such as auto bodies and white goods need a heavier twin-shaft shredder such as the TG-2200, a heavy-duty machine rated at 2000 HP (1492 kW) with a throughput of up to 80 tons per hour.
For tighter particle size control, a four-shaft machine like the TG-FourShaft 400 (2x75 kW) uses interchangeable screens from 20 to 60 mm. If your line feeds a crusher or melting furnace, a consistent fraction improves downstream efficiency.
Common Shredder Types for Scrap Yards
Understanding the main machine types helps you shortlist the right equipment quickly. Single-shaft shredders such as the TG-SingleShaft 200 (55 kW) use a hydraulic feed ram and an interchangeable screen to produce a precise, consistent particle size, making them a good fit for aluminum, copper, and brass scrap where output size control matters. Twin-shaft shredders use counter-rotating shafts with bolt-on cutting discs to shear mixed scrap into uniform fractions, and they handle bulky items such as auto bodies and white goods well. Four-shaft shredders such as the TG-FourShaft 400 add a screen basket for even tighter particle size control, which suits lines that feed a crusher or melting furnace. Heavy-duty hammer crushers such as the TG-Hammer 800 (750 kW) use high-inertia manganese hammers to fracture dense cast iron and steel billets, producing consistent charge material for downstream melting.
Key Specifications to Compare
| Model | Type | Drive | Typical Throughput |
|---|---|---|---|
| TG-LightMetal 80 | Twin-shaft, light duty | 2x15 kW | Light sheet, aluminum, cable |
| TG-AluShred 120 | Twin-shaft, swarf | 2x18.5 kW | Aluminum turnings, chips |
| TG-SingleShaft 200 | Single-shaft | 55 kW | Aluminum, copper, brass |
| TG-FourShaft 400 | Four-shaft | 2x75 kW | 20–60 mm screen control |
| TG-Hammer 800 | Hammer crusher | 750 kW | 40–60 t/h mixed ferrous (depends on feed density) |
| TG-2200 | Twin-shaft, heavy duty | 2000 HP (1492 kW) | Up to 80 t/h mixed scrap |
Drive Power and Throughput
Match motor power to your target throughput and material density. Common mid-size metal shredders process roughly 2 to 30 tons per hour depending on material and discharge size. Heavy-duty machines sit above this range: the TG-Hammer 800 reaches 40 to 60 tons per hour on mixed ferrous scrap with suitable feed density, while the TG-2200 heavy-duty twin-shaft shredder is rated up to 80 tons per hour.
Cutting Tools and Wear Parts
Bolt-on alloy tool-steel cutting discs can be replaced individually in the field, keeping maintenance cost per ton low. Reversible manganese steel hammers extend service intervals. Ask how wear parts are replaced and whether spares ship with the machine.
Electrical Configuration
Confirm whether the machine supports your plant's electrical standard. Standard 50 Hz and 60 Hz configurations let you match regional power supplies, and soft-start or VFD options protect plants with limited grid inrush capacity.
Southeast Asia Market Considerations
Buyers in Vietnam, Indonesia, Thailand, Malaysia, and the Philippines often process a mix of imported scrap and local industrial waste. Confirm that the machine handles your specific feedstock mix and that the electrical configuration matches your plant's standard. Ask about lead times and spare-parts availability, since downtime in a busy scrap yard is expensive. A supplier with in-house manufacturing can usually offer shorter lead times and better after-sales support.
How to Evaluate a Supplier
Beyond the machine itself, check the manufacturer's production capability and after-sales support. A supplier with in-house machining, welding, and electrical assembly can control quality and lead times. Ask about installation supervision, operator training, warranty, and whether a spare-parts kit ships with every machine.
Tiangong has manufactured metal shredders and crushers since 2008, operating a 12,000 m² facility with in-house machining, welding, and electrical assembly. Standard models ship in under 45 days, are CE-marked, and come with a 12-month warranty and spare-parts kit. The engineering team configures rotor knife profiles, screen mesh openings, and hopper dimensions to match your input material and downstream separation requirements.
Buying Checklist for Southeast Asian Buyers
- Define your feedstock type, density, and maximum feed size.
- Set your target output particle size and required throughput.
- Confirm your plant's electrical standard (50 Hz or 60 Hz).
- Compare cutting tool material and how wear parts are replaced.
- Ask about certification, warranty, spare parts, and installation support.
- Request a configuration matched to your material, not a generic quote.
FAQ
What size metal shredder do I need?
It depends on your feedstock and target throughput. Start from material type, density, and output size, then match drive power and shaft configuration accordingly.
What is the difference between single-shaft and twin-shaft shredders?
Single-shaft machines such as the TG-SingleShaft 200 use a hydraulic feed ram and screen for precise particle size control, while twin-shaft machines use counter-rotating shafts to shear mixed scrap into uniform fractions. Four-shaft machines add a screen basket for even tighter control.
Do you support installation and training?
Yes. Tiangong provides installation supervision, operator training, and a 12-month warranty backed by spare-parts kits shipped with every machine.
