TG-SingleShaft 200 Single-Shaft Metal Shredder

Screened Single-Shaft Shredding for Homogeneous Non-Ferrous Streams

The TG-SingleShaft 200 is designed for processors handling relatively homogeneous feed streams-light aluminum profiles, copper wire, brass turnings, thin sheet offcuts-where the priority is precise particle size control rather than the brute tearing capacity of a twin-shaft unit. A horizontal rotor carrying bolted cutting knives rotates against a fixed bed knife, shearing material that is pushed into the cutting zone by a hydraulic ram. A screen beneath the rotor controls discharge size, holding material in the chamber until it passes through the selected perforation.

The advantage over twin-shaft designs is particle size consistency. Twin-shaft shredders discharge whatever falls through the shaft gap, producing wider size variation. For buyers feeding briquetting presses, granulators, or smelting furnaces that require consistent charge geometry, the screened output reduces the need for secondary sizing.

Specifications

The hydraulic feed ram pushes material against the rotor at a controlled rate, preventing the surge-loading that causes motor overloads on gravity-fed machines. Ram stroke is adjustable-denser copper and brass require slower ram advance than light aluminum to avoid rotor stall.

When to Choose Single-Shaft Over Twin-Shaft

Twin-shaft shredders excel at gripping and tearing mixed, irregular scrap where feed geometry varies unpredictably. Single-shaft shredders are better suited to streams that are already somewhat uniform: aluminum extrusion offcuts, copper wire bundles, brass turnings, stamped sheet skeletal waste. The screened output gives a narrow particle size range that twin-shaft designs cannot match.

For wire and cable bundles, the ram also prevents the rotor from grabbing and wrapping long strands around the shaft. If wrapping does occur, the ram reverses automatically to release the tangle before resuming forward feed.

Cutting System and Maintenance

• Rotor knives: Hardened tool steel, D-type or V-type profile, bolt-on
• Bed knife: Adjustable clearance, bolted, replaceable without rotor removal
• Screen: Bolted perforated plate, available in 10, 15, 20, 30, and 40 mm
• Side liners: Hardox wear plates, bolted

Knife clearance should be checked weekly and reset after each sharpening cycle. Both rotor knives and bed knife are bolt-on replacements that can be changed without removing the rotor assembly.

Application Boundaries

Rated for non-ferrous and light-gauge materials only. Not designed for dense ferrous stock such as engine blocks, railway rail, or thick-walled structural sections-these exceed the rotor torque rating and will stall the machine or damage cutting knives. For mixed scrap streams containing ferrous and non-ferrous, a twin-shaft shredder such as the TG-2200 is more appropriate as the primary stage, with the single-shaft positioned downstream for final sizing.

Confirm material hardness, maximum stock thickness, and whether the feed contains tramp ferrous before ordering. A magnetic separator upstream is recommended if the material stream may contain ferrous contamination.

Drive and Control

The PLC manages ram stroke, rotor speed, and automatic reverse on overload. Soft-start is standard; VFD is available for applications requiring variable rotor speed to optimize cutting performance across different material types.

Wear Parts and Support

Spare rotor knives (D-type and V-type), bed knives, screens (10–40 mm), and liner plates are available as individual replacements. Our engineering team can configure knife profiles and screen sizes to match specific feed material characteristics. Each machine ships with a spare-parts kit; standard lead time for replacement wear parts is under 45 days. Installation supervision, operator training, and a 12-month warranty are included.
