TG-TwinShred 300 Twin-Shaft Metal Shredder

Mid-Range Shredding Power for Yards Between Batch Work and Full Production

Scrap yards and recycling workshops that collect between one and three tons of light metal scrap per day rarely fit either end of the shredder market. A light-duty machine runs all day and still falls behind; a heavy industrial line sits idle more than it cuts, while its power bill and tooling budget never stop. The TG-TwinShred 300 is built for exactly this middle ground: a twin-shaft metal shredder with 2 x 45 kW geared motors, an 800 x 600 mm cutting chamber, and a rated throughput of 3 to 6 tons per hour on light ferrous and non-ferrous scrap.

The machine targets the bottleneck that keeps growing yards from growing faster: unprocessed scrap occupies storage space, loses value at the scales, and ties up labor that could be sorting, loading, or winning new accounts. By reducing sheet steel, aluminum profiles, cable, and appliance casings to a uniform particle size in a single pass, the TG-TwinShred 300 turns loose, awkward feedstock into dense, flowable shred that loads faster, weighs cleaner, and feeds downstream separation equipment without bridging.

Twin-Shaft Cutting Architecture

Two counter-rotating shafts carry interlocking cutting discs in a low-speed, high-torque configuration. When a piece of scrap cannot be sheared in one pass, the shafts stop, reverse, and re-engage from a new cutting angle automatically, without an operator standing at the hopper. This auto-reverse behavior is the main reason twin-shaft machines keep running on mixed, unpredictable scrap where single-rotor designs stall or trip their protection.

• Bolt-on alloy tool steel discs: worn or damaged discs are replaced individually in the yard instead of swapping a complete shaft assembly, which keeps knife inventory and spare-part cost predictable.
• Counter-knife combs: adjustable combs between the discs stop long, springy strip material from wrapping around the shafts, which is the classic cause of unplanned stops on profile and cable feed.
• Sealed, outboard bearing housings: bearings sit outside the cutting zone, protected from chips and dust, so daily cleaning does not turn into a bearing replacement cycle.
• Geared drive sized for shock loads: the 2 x 45 kW motors run through helical gearboxes selected for the shock loading of mixed scrap rather than for peak nameplate figures alone.

Specifications

What the Design Does for Cost per Ton

Buyers comparing shredders at this size should weigh three numbers that never appear on a quotation: electricity per ton, tooling cost per ton, and hours lost to jams. The low cutting speed keeps absorbed power relatively steady instead of spiking with every heavy piece, which is easier on both the electricity meter and the motor protection. Because discs are bolted on rather than welded to the shaft, a damaged disc is a workshop job rather than a workshop week: rotate, re-sharpen, or replace individual discs on your own schedule. And the auto-reverse control clears most jams by itself, so one loader operator can keep the machine fed without a second person on standby.

Typical Applications

• Sheet steel offcuts and light-gauge fabrication scrap
• Aluminum window, door, and extrusion profiles
• Copper and aluminum cable, stripped or lightly insulated
• WEEE casings and small appliance housings, after battery removal
• Mixed light scrap from manufacturing estates

Before You Order

Throughput depends on feedstock mix, target particle size, and loading pattern; the figures above are rated values for typical light scrap, not guarantees for every material. Before quotation, our engineers confirm your dominant scrap types and their largest cross-sections, your target output size, the available power supply at the site, and whether an infeed or discharge conveyor should be matched to the chamber height. The disc and comb configuration is selected for your material list before the machine is built.

Frequently Asked Questions

Can it take a full small appliance or radiator?

The 800 x 600 mm chamber accepts whole small appliance casings and complete radiators. Larger white goods should be pre-cut or fed to a larger model in this range; the chamber dimensions above are the practical limit for uncut pieces.

What does cutting-system maintenance involve?

Routine care is a daily visual check, periodic disc rotation and re-sharpening, and individual bolt-on disc replacement when a disc is damaged. Exact intervals depend on your feedstock abrasiveness and are confirmed during commissioning.

How is the output particle size controlled?

Particle size is set by the disc width and comb configuration selected for your order. If your downstream equipment needs a different size later, the configuration can be changed with the machine, without replacing the shafts.

Do you support 60 Hz power supplies?

Yes. Motors and the control cabinet are configurable for 380 V / 50 Hz or 460 V / 60 Hz, so the same machine can be commissioned on either supply standard.
