Compact Twin-Shaft Shredding for Light-Gauge Metal
The TG-LightMetal 80 is a compact twin-shaft shredder built for small to medium-scale metal recyclers, fabrication workshops, and manufacturing facilities that generate light-gauge metal waste but do not need the throughput or footprint of a heavy industrial shredder. It processes thin sheet steel, aluminum sheet and profiles, copper and brass offcuts, electrical cable, and light mixed metal scrap-densifying these low-bulk-density materials into manageable fragments for recycling or downstream processing.
Key Specifications
The wide, low-profile feed hopper is sized for sheet stock and profile offcuts that arrive flat or in long strips-material that tends to bridge in narrower hoppers designed for chunkier scrap. The twin shafts grip and pull sheet material into the cutting gap, shearing it into fragments rather than folding or crushing it, which keeps the output loose and uniform rather than compacted into balls.
Who Needs a Light-Duty Metal Shredder
Not every metal recycling application requires a 750 kW hammer crusher or a 2000 HP twin-shaft shredder. Many facilities generate steady volumes of light-gauge metal waste that is too thin and bulky to sell directly to scrap dealers at a reasonable price, but not dense enough to justify processing on heavy machinery:
- Fabrication shops: Sheet metal offcuts, skeleton waste from stamping and laser cutting, aluminum profile cutoffs
- Electronics recyclers: Sheet metal housings from computers, appliances, and electronic equipment (after component removal)
- HVAC and ducting manufacturers: Galvanized sheet offcuts, aluminum duct waste, copper pipe and fitting rejects
- Small scrap yards: Light mixed metal from household collections, bicycle frames, aluminum window frames, light gauge fencing
For these applications, the TG-LightMetal 80 reduces volume and densifies material enough to make storage, transport, and sale to foundries or mills practical. The 30 kW drive keeps operating costs and power supply requirements modest-a standard industrial three-phase connection is sufficient.
Cutting System and Wear Parts
The shafts carry bolt-on cutting discs with alloy tool-steel tips. The disc profile is optimized for thin-gauge material: the cutting edges are closer together than on heavy-duty shredders, producing finer fragments from sheet stock. Discs are individually replaceable without shaft removal.
- Cutting discs: alloy tool steel, bolt-on, individually replaceable
- Side liners: bolted wear plates, AR400 grade
- Shaft seals: grease-purged labyrinth seals
- Discharge: open discharge or optional screen for particle size control
Material Suitability and Limitations
The TG-LightMetal 80 is rated for light-gauge non-ferrous and thin ferrous material:
- Aluminum sheet and profiles up to 5 mm thickness
- Steel sheet up to 3 mm thickness
- Copper and brass sheet, pipe, and offcuts
- Electrical cable and wire (for pre-size-reduction before granulation)
- Light mixed metal scrap with individual pieces under 3 mm wall thickness
The machine is not designed for solid bars, thick-walled pipe, castings, engine components, or any material exceeding 5 mm thickness in steel or 8 mm in aluminum. Feeding materials above these limits will stall the rotors and may damage cutting discs. For heavier stock, a larger shredder from the TG range is more appropriate.
Drive and Electrical Configuration
The two 15 kW motors are available in 50 Hz or 60 Hz configuration. The PLC control system monitors motor load and automatically reverses shaft rotation on overload. Soft-start is standard. The machine's modest power draw means it can be installed on a standard industrial three-phase supply without the transformer upgrades that heavier shredders may require-an important consideration for smaller facilities.
Compliance and Certification
The machine frame and guarding carry CE marking per the Machinery Directive. The manufacturing facility operates under ISO 9001 quality management. UL-listed control panel configuration is available for North American buyers on request. The compact footprint allows installation in existing workshop spaces without major civil works.
Buyer FAQ
Request a Detailed Proposal
To prepare an accurate quotation, include your typical material type and thickness, estimated monthly volume, target output fragment size, site power supply (voltage and frequency, 50 Hz or 60 Hz), and available floor space. Mention whether you need the shredder as a standalone unit or integrated with a discharge conveyor or collection bin.
